AV:RetroTINK-5X Pro

The RetroTink 5X Pro is an advanced video upscaler designed by Mike Chi. It is the latest offering from the RetroTink line of graphics upscalers and line-doublers.

How To Use The RetroTink5x Pro - A Beginner’s Guide
The Retrotink 5x Pro is a product designed to solve the problem of using retro video game consoles with modern flat panel displays. If you’ve arrived at this guide, you’re probably aware of some problems when trying to play older video game systems on a newer TV's.

HDMI vs Analog
In many situations, the cables that came with your game system will not be compatible with the modern digital HDMI inputs on your TV. One of the main features of the RetroTink 5X Pro (abbreviated as the “Tink 5x”) is to convert these signals into an HDMI format your modern display can understand.

Correct Image Processing
In the cases that your display does have the correct hook ups to connect your console, there’s still a good chance that the resulting output will be blurry, distorted and laggy. This is because most displays are designed with video content in mind, and the video processing used to handle video isn’t a good fit for retro consoles. Features like minimal and consistent latency, integer scaling and proper handling of 240p are almost always missing when using a flat panel’s included analog inputs.

Lag
The Tink 5X by design is an extremely low lag device, and includes advanced modes to operate even more quickly (with trade offs to other features, see Triple Buffer vs Frame Lock Mode and 1080p (Min-Lag) for more info).

lag (aka latency) is the measurement of the time between a controller button input to when the action is shown on screen. Every electronic device takes a little bit of time to do its job. In the context of gaming, this includes the controller itself, the video game console, any upscalers or splitters in the signal chain, and the display. Having too much lag in a setup can make gameplay feel sluggish, unresponsive, and in extreme cases unplayable. This is why enthusiasts seek devices (controllers, displays, upscalers, etc.) that minimize latency. Devices that do their job as quickly as possible are often referred to as "low lag" or "virtually no lag".

when seeking products that are low latency, it's helpful to know that anything less than a frame in a 60fps signal is colloquially considered very low lag. Often milliseconds (ms) are used to measure lag. 1 frame of a standard 60fps signal is equal to approximately 16.7ms.

Just Play the Damn Game™
Thanks to Mike Chi’s research and engineering, the Tink 5x is one of the best products on the market specifically built to address the peculiarities of retro video game analog signals. While a complex engine of tweakability lies under the hood for enthusiasts, the Tink 5x prioritizes ease of use so anyone can get their console up in running.

Here are the basic steps anyone can take to get a great experience with their retro video game console:


 * 1) Connect the Tink 5x to your display using an HDMI cable.
 * 2) Connect your video game console’s video and audio to the Tink 5x using a supported cable (link to supported inputs section).
 * 3) Power on the Tink 5x using the included MicroUSB cable - many TV’s will have a USB hookup on the back that will work as a power source.
 * 4) Using the included remote, select the appropriate input from the Input Source menu. (This choice depends on the cable you are using to connect your video game console to the Tink 5x, see Supported Inputs section for more information).
 * 5) Using the included remote, select the appropriate output from the Output Res. menu. (For most TV’s, 1080p (Fill) is a great “all around” choice.)

And that’s it! You don’t have to be an A/V engineer to get remarkable results from the Tink 5x, all the hard work is done behind the scenes. Understanding jargon such as automatic phase detection, polyphase scaling or motion adaptive deinterlacing isn’t required for you to gain the benefits and enjoy your retro consoles on a flat panel with great results.

Supported Inputs
The Tink 5x supports nearly every major analog video format used by retro video game consoles. Please see the Inputs Source section for more information about supported resolutions and modes.

Composite
This is the “standard yellow video cable” most people are familiar with. Composite video cables were found on consoles ranging from the NES all the way through the Xbox 360 / PS3 era of gaming.

To use composite video: plug your cable’s video RCA plug (typically yellow in color) into the Tink 5x’s “Y” labeled input, and your left and right audio into the “L” and “R” inputs respectively. Then, select Composite from the Tink 5x’s Input Source menu.

SCART-CV
The Tink 5x supports composite input over the SCART connector input. SCART was not widely used in the United States but was common in Europe, and video game consoles sometimes featured composite video and audio connections over SCART.

Note that S-Video (Y/C) video formats are not accepted through the SCART connector input.

To use SCART-CV, plug in an appropriately wired SCART cable or use RCA cables for video/audio with a compatible SCART breakout adapter, and select SCART-CV from the Tink 5x’s Input Source menu.

S-Video
S-Video is an iteration of composite video that features two parts of the composite signal (Y and C) across two separate wires. Using S-Video cables are typically regarded as a visual improvement over “standard” composite cables. Consoles that supported S-Video output include (but not limited to) PlayStation, Nintendo 64, Saturn and Dreamcast.

To use S-Video with the Tink 5x, plug the S-Video cable into the Tink 5x’s “Y/C” input, and your left and right audio into the “L” and “R” inputs respectively. Then, select S-Video from the Tink 5x’s Input Source menu.

YPbPr / Component
YPbPr or "Component" video is a high quality analog standard that uses 3 RCA cables to carry separate parts of the video signal. Component video was featured on consoles such as PlayStation 2, PlayStation 3, Xbox, Wii, and Gamecube (model # DOL-001 only).

To use YPbPr with the Tink 5x, insert the Y RCA plug (typically colored green) into the Tink 5x’s “Y” input, insert the Pb RCA plug (typically colored blue) into the Tink 5x’s “Pb” input, and insert the "Pr" RCA plug (typically colored red) into the Tink 5x’s “Pr” input. For audio, insert your left and right audio into the “L” and “R” inputs respectively.

Then, select YPbPr or YPbPr (SDP) for from the Tink 5x’s Input Source menu.

Review the Input Source section of the guide for more information concerning differences between YPbPr and YPbPr (SDP) modes.

SCART-RGB
The Tink 5x supports RGB input through the SCART connector input. SCART was not widely used in the United States but was common in Europe, and video game consoles often featured RGB video and audio connections over SCART. To find out if your console supports RGB over SCART, check out the Systems Section from the RetroRGB merger, or the original RetroRGB webpage while the Wiki under construction.

Compatibility
Tink 5x is designed to accept RGB over SCART in the "EuroSCART" variant and NOT JP21. Though JP21 uses the same style connector, it is not compatible with the Tink 5x and may damage your hardware.

Sync
The Tink 5x accepts sync on luma, sync on composite and c-sync RGB over SCART configurations. Check with your SCART cable manufacturer to ensure compatibility with the RetroTink 5x Pro.

Note that TTL sync is not supported by the Tink 5x and may damage your hardware.

31khz Signals
The Tink 5x can accept 31khz RGB signals with the use of a compatible sync combiner device. This allows for "VGA" input from compatible sources / resolutions. Sync combiner products include the HD15-2-SCART and VGA2SCART. A common implementation of this option is accepting Dreamcast "VGA" using a compatible VGA cable. Other options include building a sync combiner directly into the SCART cable, such as the Retro Access Dreamcast 15khz/31khz SCART cable.

Triple Buffer vs Frame Lock Mode
''The following is from the official RetroTINK-5X manual. I would like to come back to this and simplify it a bit and explain the "Chrono Cross" problem.''

The RT5X has two modes for generating the output video timing. Triple buffer uses a full frame memory and an externally derived clock to maintain a constant 60 frames/sec. The lag varies between approx. 0.25 to 1.25 frames in this mode.

Triple buffer offers the highest compatibility across all equipment and immunity against sync loss/resolution changes at the expense of increased lag and occasional judder due to the need to repeat/drop frames.

Frame lock utilizes the video ADC and console as the base clock. The output frame rate follows the original console exactly with a fixed lag of approx. 0.25 frames. Frame lock may not be compatible with some TVs and capture cards, depending on the console’s frame rate. Frame lock is automatically engaged for 480p, 576p, 720p and 1080i sources since they derive from modern equipment that generally follow standard refresh rates.

Console Specific Horizontal Sampling Modes
The Tink 5X includes "Optimal Timings" to get the sharpest output from your console. Here are the included presets:

 * 4K24 (for 60 Hz sources) and 4K25 (for 50 Hz) sources. Frame lock on for 60 Hz sources changes to 4K30.
 * These modes are considered experimental and provided without support or guarantees.
 * New 1080p (Min-Lag) mode operates the RT5X as a line doubler to achieve ~1 ms when frame lock is turned on for 240p, 480i and 480p sources.
 * 720p source can be scaled to 1920 x 1440 or 2560 x 1440.
 * 240p and 540p modes have been removed to save space.
 * "Pre-scaler" option in the [Interp./Deint.] menu to convert 480p and 720p sources to 240p, before re-upscaling.
 * Optimal timings re-enabled for composite and S-video sources.
 * Option to enable optimal timings for interlaced sources.
 * Hi-Res 512 and 858 optimal timing modes added.
 * "Pre-emph" filter now goes down to -5.
 * Option to load profile on power up in the [OSD] -> Startup Profile option.
 * Press and hold remote control button to keep incrementing/decrementing option.
 * Press "back" button 6 times rapidly to load default profile.
 * Variety of bug and crop fixes.

Version 2.39 - Special Holiday Edition!
Originally released December 21st, 2021

First of all, thank you so much everyone for making the RetroTINK-5X a reality. I could not have imagined the interest and growth that this project has experienced over the past year. This was all possible only due to the tremendous support from the community.

To show our appreciation, we wanted to make this holiday season update extra special. The entire system has been re-written with a full menu system to support new options and features plus free-scaling, CRT effects and an improved polyphase scaling engine!

There's a lot to digest and the manual needs to be completely re-written, which will take some time. For now, check out this stream with RetroRGB where we go over everything, which will serve as a handy video tutorial and reference.

We hope that this will give you many more hours of enjoyment. It's been a true honor and pleasure creating this for you.


 * Quick notes:
 * The menu system relies on the remote. The Top Left button calls up the OSD. Use the arrow keys to navigate/toggle through settings. Use the OK button to select an option. The Back button exits the OSD.
 * The remote overlays should largely be compatible. When the OSD is off, each button serves as a direct short cut to the corresponding page in the menu.
 * The system always powers on to the default profile as a safety measure.
 * Right now, re-flashing the firmware will erase your profiles, so please be careful.
 * The input source can be directly cycled using the physical 'Input' button on the device as a fail safe in case the remote is inoperative.

Version 1.999
Originally released November 5th, 2021


 * Fixed glitch in some scanline modes.

Version 1.99
Originally released October 11th, 2021


 * Fixed (minor) blue channel interpolation error.
 * Fixed clamping error.

Version 1.98
Originally released October 10th, 2021

A friendly reminder due to concerns about too many adjustments and settings as improvements/features are implemented: You can always use the RT5X with default settings (1080pFill/Generic) and get an experience that is arguably at least 90% as good if you never want to deal with any of this.
 * Fixed "Green Push" bug in 240p/480i modes introduced in the last version.
 * Fixed aspect ratio bug that in 720p -> 240p downscaling in 4:3 mode.
 * Fixed bug that caused a slight vertical shift when engaging scanline mode.
 * Separated auto-phase thresholds for 240p/480p/360p for more reliable operation.
 * HDMI aspect ratio flag is set to "4:3" for 1440p output to improve compatibility with TVs that do not provide manual controls.
 * PAL "stretch" modes now implemented for composite and S-video inputs, bringing them in line with the RGB and YPbPr modes.
 * The "16:9" mode for 1200p with a 480p input is replaced with a "3:2" mode for use with Dreamcast.
 * 480p sources now have three sampling modes: DTV-A, DTV-B, Generic 4:3 and Generic 16:9.
 * Enhanced Auto-Phase control and regeneration algorithm for "4:4:4" output quality with DTV-A and DTV-B modes with component video inputs.
 * The new, enhanced DTV "4:4:4" re-sampler may take a few seconds to analyze and converge to the optimal settings.
 * Most setups will look best with DTV-A. If something looks off, use DTV-B as a fallback.
 * PS2 looks best with the EDTV LPF off.
 * Xbox, due to video noise, appears to work best with EDTV LPF on.
 * You can use any combination of settings for GCN and Wii, due to their native 4:2:2 output.
 * New CRT effects with improved mask generation engine:
 * Slot Mask - resembles a high resolution slot mask CRT, replacing the old version which was too coarse.
 * Aperture Grille: Same as before
 * Aperture Grille 2: Equivalent to the old "PVM" mode
 * PVM 600 TVL: A finer grille with highlights to mimic a mid-range PVM
 * FV310: A coarser grille with highlights to mimic a consumer Trinitron
 * Consumer 1: Coarse slot mask with no visible scanlines mimicking a low-resolution consumer tube
 * Consumer 2: Coarse slot mask of a different pattern with a slight scanline effect
 * Note: The "80's CRT mode" would be equivalent to Consumer 1, Pre-Emph -3, Notch Filter with a composite source.

Version 1.84
Originally released September 21st, 2021


 * Reworked 50 Hz 1080p modes for RGB/YPbPr inputs:
 * 1080p (Fill) is a 4x (288p) or 2x (576i) integer scale to 1152p with a tiny amount of vertical overscan cropping.
 * 1080p (Over) adds an vertical stretch of ~20% to undo "lazy" PAL ports that place 240p/480i artwork in a 288p/576i frame.
 * 1080p (Under) scales the 288p/576i content to exactly 1080p
 * Use the "Up" and "Down" buttons to center the image vertically as needed.
 * Optimal timings now available for 50 Hz RGB/YPbPr inputs:
 * Only enabled for 1080p (Fill) and 1080p (Over) output modes.
 * Highly experimental.
 * Fixed some minor GBI mode bugs.
 * Enhanced auto-phase algorithm to avoid false locks on black screens.

Version 1.77
Originally released September 9th, 2021

Reminder: Both CRT effects and Smoothing filters look best in 'Generic' mode. Optionally set the pre-emphasis filter to -1 for a softer effect.
 * Reverted AG scanline option to previous mask width
 * Enhanced gamma and saturation compensation for all scanline modes
 * EDTV LPF is a separate setting from SDTV modes
 * I generally recommend leaving the EDTV LFP to 'off' for the sharpest image in DTV 858 optimal sampling/auto-phase. Only turn it on if you see noise/jailbars.
 * Fixed screen tear bug in 480p -> 1080p (Under)
 * Fixed vertical hold (rolling screen) glitch for odd NTSC and PAL systems that uses non-standard sync lengths (mostly old home computers and PAL Atari Jaguar).

Version 1.74
Originally released September 4th, 2021


 * Added 'Smoothing Filter'
 * Enable by cycling into the 'Interpolation' menu (Vol+ button on remote).
 * Current algorithm works best on 480p 3D content (i.e. Xbox, GCN games). Lower resolution content might be too rough.
 * Smoothing filter is also used to enhance the performance of the Motion Adaptive Deinterlacer, although the effect is subtle.
 * Reverted some settings that might have caused instability with SNES and other consoles. For difficult systems, like the SMS and NEOGEO AES use the 'Strong' LPF setting. For all other systems use 'Off', 'Light' or 'Medium'.
 * LPF for 480p sources automatically engaged for all LPF settings except the 'Off' position.
 * 'Aperture Grille' setting now uses a coarser mask than 'PVM'. Previous setting was too similar.
 * Added mild Gamma boost to the scanline settings to overcome brightness loss.
 * Fixed a variety of cropping issues in various NTSC and PAL video modes.

Version 1.67
Originally released August 6th, 2021


 * Added new scanline and CRT effects.
 * Intensity modulation (25%, 50%, 75%): Variant of polyphase scanlines where the width of the "beam" is proportional to brightness, mimicking a CRT. At 50%, this mode has a similar visual characteristic to a 800-900 TVL BVM.
 * Slot Mask, Aperture Grille, PVM: Adds vertical lines to mimic a CRT's mask. Slot mask attempts to recreate an arcade CRT. Aperture Grille attempts to recreate a consumer Trinitron. PVM attempts to recreate a 600 TVL professional monitor.
 * Due to the high amount of fine detail in the slot mask mode, I recommend using the 1440p output mode.
 * Simulated scanlines work by artificially darkening the picture. Normally, I am strongly against modifying your TV's picture controls beyond strict "neutral", but in this case, try adjusting your TV's various brightness/backlight controls as well as activating advanced processing like "dynamic contrast". I've found that they can be helpful at compensating for the lost intensity.
 * Added "Pre-emphasis Filter" to soften or sharpen the image. The default value of "0" adds no processing. Negative values blur the image, and can be a good match with the CRT effects to create a soft look. Positive values sharpen the image and can be helpful with systems like the 2/3-Chip SNES.
 * PS1 320 optimal sampling is now a separate setting from Genesis since the timings differ enough to cause artifacts.
 * Added 540p output for use with HD-CRTs.

Version 1.55
Originally released July 20th, 2021

Note: Generic modes are unaffected either way since they do not contain sharp color transitions.
 * Some optimal modes are capable of outputting "444" chroma sampling (thanks to Extrems for the idea):
 * Added LCD overlay effect to the "Scanline" menu. For this to work:
 * The H. Sampling must be in an optimal mode.
 * The output mode must be using an integer vertical scaling factor.
 * Tuned auto-phase algorithm - initial detection of correct phase will take longer but it should eliminate random hunting.

Version 1.29
Originally released June 17th, 2021


 * Fixed some alignment problems in GBI 360p mode.
 * Added "240p" style scanlines to GBI content.
 * Fixed YPbPr detection glitch in version 1.28.
 * Cleaned up 480p cropping.

Version 1.28
Originally released June 15th, 2021


 * Added 360p support for the GBI. Possible output resolutions:
 * 1080p (FILL): 6x integer scale with optimal sampling/autophase
 * 1080p (OVER): 6.75 interpolated scaling to use the full vertical height of the display
 * 1200p: 7x integer scale with optimal timing/autophase
 * 1440p: 8x integer scale with optimal sampling/autophase

Grumpy disclaimer time! It's up to you to get GBI and 360p output from your Gamecube setup! We cannot provide support for the use of 3rd party equipment and there are simply too many variations for us to be able to keep up with.

We can confirm that a PAL GCN with a RGB SCART cable (use one designed for PAL consoles NOT NTSC) works as well as the official OEM component cables and the Insurrection Industries Carby with an external HDMI -> YPbPr converter box. The RGB approach seems to have some image quality issues, though, so we'd recommend a solution that uses the GC's digital AV port.

Unfortunately the Carby Component Cable does not work. The HD Retrovision on a PAL GCN also does not work. We do not know if a modded GCN works, but are told that it should.

Version 1.24
Originally released June 5th, 2021


 * SDTV LPF has now four settings: Off/Light/Medium/Strong.
 * DTV 858 Optimal Sampling for 480p sources is now enabled for 1440p output modes. Please set your display to "16:9" for the correct final aspect ratio.
 * Scanline generator now has 25%, 50%, 80% and 100% (integer) modes.
 * 480p style scanlines can be applied to de-interlaced 480i content.

Version 1.2
Originally released May 26th, 2021


 * 480p sources (4:3 aspect only) now use automatic optimal sampling/phase (858 pixel DTV) when the output resolution is 1080p (FILL), 1080p (UNDER) and 480p. This brings pixel perfect sampling to 480p games on DC, PS2, XBOX and GCN. When active, the 'Generic 4:3' is replaced with 'DTV 858' under the 'H. Sampling' Menu.
 * Improved standard definition LPF to reduce noise without compromising sharpness.
 * Fixed chroma offset error resulting in 1-2-pixel wide color shifts (big thanks to Fudoh).
 * Fixed incorrect aspect ratio flag that caused 4:3 squeeze on 1080p modes.
 * Fixed 720p gain control error that caused variable brightness.
 * Fixed scanline generator bug that caused false colors on bright scenes.
 * Fixed 720p stability issues in pass-thru and down scaling.


 * Fixed some sync problems:
 * Fixed NEOGEO sync for AES and MVS-1F consoles. Activate fix by entering NEOGEO optimal timing mode.
 * SMS should be stable now as long as the 'LPF' is enabled.
 * Both fixes seem to be most reliable with HDRV cables. You might need to cycle back to the NEOGEO mode in some cases. For frequent NEOGEO users, I would still recommend a MVS-1C based system.


 * Added 576p and 1440p output modes to 288p/576i/576p sources.
 * Improved 'no-signal' detection to prevent glitched output when source is removed.
 * Minimized glitched image during resolution changes.
 * General improvements in clock stability.

Introduction
The RetroTINK-5X (RT5X) is an advanced video scaler for connecting retro consoles to modern HDTVs. Multiple input options: component, SCART RGB, composite and S-video are accepted. The standard definition processor in the RT5X is capable of decoding NTSC, PAL and PAL-60 formats. The component and RGB ports can digitize analog high definition video up to 720p and 1080i. The custom scaler engine is implemented on a FPGA, enabling low-lag operation with outputs up to 1440p.

Specifications
* Due to chipset limitations, 720p and 1080i input resolutions are sampled at 4:2:2. All others are oversampled to achieve the equivalent of 4:4:4 chroma resolution or greater at the base sampling rate.

Caution - Read Carefully Before Use

 * 1) Only use SCART cables that provide sync using 75 ohm terminated luma or composite video or buffered/attenuated CSYNC. Use of unbuffered TTL CSYNC is expressly prohibited and may result in incompatibilities and/or damage. Under no circumstance is RetroTINK LLC responsible for the use of improperly designed SCART equipment.
 * 2) Only use the RetroTINK provided firmware update tool for USB updates. Attempts to flash the device using alternate methods, such as directly via the ICD pins on the PCB, may result in device malfunction and damage. Under no circumstance is RetroTINK LLC liable for failure due to improper firmware flashing.
 * 3) Use a high-quality USB power source capable of supplying at least 1 A of current to your RT5X. Low quality USB power supplies may result in device malfunction and/or video noise. It is also important to use a good quality USB cable. Poorly manufactured cables drop voltage under high currents, which may result in video noise and device malfunction.
 * 4) The RT5X is a high quality video scaler with minimal processing, such as artificial noise reduction, to accurately reproduce the original signal from the game console. For good results, it is imperative that high quality cabling is used to avoid noise and interference. We generally recommend HD Retrovision component cables or high quality shielded/coaxial SCART RGB cables. Generic, low-cost SCART cables will show interference, noise, unreliable sync, picture drops and in the worst cases, may result in damage to your RT5X. We recommend shielded SCART cables using composite video as sync with 75 ohm source impedances, per the standard. Unshielded S-video cables will almost certainly show chroma checker boarding, especially at higher output resolutions.
 * 5) Use common sense when handling the RT5X - it is an expensive piece of electronics. Do not drop, crush or immerse your RT5X in a liquid. The warranty does not cover accidental damage and/or abuse to the unit.

 * 11) SCART Input - Both RGB and CVBS can be accepted by the RT5X’s SCART port.
 * 12) S-Video Input - Y/C video using a standard DIN-4 connector. Shares audio with YPbPr.
 * 13) YPbPr Input - Component video using standard RCA jacks. Composite sources can be connected to the green Y jack.
 * 14) Stereo Audio Input - The audio input for the YPbPr and S-Video ports.
 * 15) Digital Video Output - For connecting to your HDTV.
 * 16) USB Port - Supply the RT5X with a source capable of at least 1 A of current. The USB port is also used for connecting to a Windows PC to update the firmware.

Quick Start
The RT5X is designed to be extremely easy to use and to produce an excellent picture with minimal adjustment and setup.
 * 1) Connect your RT5X to a power source via the microUSB port.
 * 2) Connect your RT5X to a HDTV via the digital video port.
 * 3) Connect your RT5X to your console using one of the video inputs.
 * 4) Press the ‘Input Button’ until the LED light indicates the correct source.

Your RT5X should now be outputting a CEA-standard compliant 1920 x 1080 to your HDTV using a high quality polyphase bilinear sharp scaling filter. If you are happy with the results, please proceed with gaming and read no further! Read the next sections to learn how to configure your RT5X to output more advanced modes to get the most out of your system.

Advanced Configuration
The RT5X uses an OSD to configure the various possible settings on the device. Pressing the ‘Menu Button’ calls up the OSD, which is displayed on the top left hand corner of the screen. The first line of the OSD shows the displayed menu option (e.g., in the above screenshot, the Deinterlacer Mode). The second line of the OSD shows the selected setting for the option (in this case, Motion Adaptive). A full description of the menu options and possible settings is shown below:

Firmware Upgrade
The RT5X has the ability to upgrade the firmware over USB using a PC-based application. No special tools are needed. RetroTINK does not support Mac OS or any other platform/tool/protocol/standard/format and has no plans to do so.

Firmware upgrades requires that the RT5X be started in bootloader mode. Hold the ‘Menu Button’ down while connecting the RT5X to a PC via a microUSB cable. The LED indicator should remain solid RED.

Follow the instructions on the RetroTINK website to complete the update process. If the upgrade process fails, simply restart by powering off the device and re-entering the bootloader. It is not possible that a genuine RetroTINK device can be ‘bricked’ by a failed firmware update.

To exit bootloader mode without upgrading, disconnect the microUSB cord from the RT5X and reinsert without holding the ‘Menu Button’ down.

Details and files may be found on www.retrotink.com once firmware updates are released.

'''ONLY UPDATE THE RT5X USING THE PROVIDED SOFTWARE. ATTEMPTS TO FLASH THE FIRMWARE USING OTHER METHODS WILL RESULT IN NON-WARRANTY DEVICE FAILURE.'''
