TG16:TEOS

This OS is incompatible with the Turbo EverDrive V1

TEOS is an alternate operating system for the Turbo EverDrive V2.5 which offers various new features and bug fixes.

Features

• Allows the TurboGrafx or PC Engine to use the Turbo EverDrive V2.X as a Super System Card. This avoids potentially damaging memory bus-fighting that occurs when booting the Super System Card software on the original Turbo EverDrive OS.
• Adds the ability to "Backup RAM" contents to and from the Turbo EverDrive's SD card.
• Adds the ability to copy the contents of a "Memory Base 128" addon to and from the Turbo EverDrive's SD card.
• Adds the ability to use the Japanese "Tennokoe Bank" HuCARD utility.
• Different looking main menu with a higher resolution font.
• Various game-specific fixes listed on the project's GitHub.

Setup

1. Format a 32GB or smaller micro SD card as FAT32.
2. Download and extract the latest release's zip from the GitHub releases page.
3. Copy all of the extracted contents to the root of the SD card. If you are updating TEOS, do not overwrite any files or you may lose saves.
   • At this point, TEOS will be listed in the Turbo EverDrive menu and can be run from there. However, if you'd like to completely replace the EverDrive OS with TEOS, rename TEOS.PCE to OS.PCE and move it into the TBED folder on your SD card.
   • If you are using a Turbo GT or Turbo Express, use the TEOS-GT.PCE file instead, as it will make text more readable on the LCD screen.
4. Copy any desired games to the root of the SD card. Note that folders are supported, so you can place games in separate folders such as Games, Translations, and Homebrew.
5. Safely eject the SD card and insert it into the Turbo EverDrive.
6. On the Turbo EverDrive cartridge itself, look for a physical switch. Slide it to the "PCE" position if your system is a PC Engine or slide it to the "TG-16" position if it's a TurboGrafx-16.
7. Insert the Turbo EverDrive into your console and turn it on. It should boot to a white screen followed by the TEOS menu.
