Xbox 360:RGH/RGH1.2

RGH1.2 combines RGH1-like PLL slowdown with Glitch2 images to allow reliable glitching of Falcon/Jasper consoles with split CB (post 14699 kernel). RGH1.2 V2 ports this hack to Trinity/Corona consoles as well as fixing a few issues on Jaspers.

Programming the Glitch Chip

 * 1) Plug the cable from your programmer into the chip programmer.
 * 2) *If you are using an xFlasher, ensure the switch is set to.
 * 3) *CoolRunner: Slide switch to "PRG".
 * 4) Open J-Runner with Extras. Click "Program Timing File" in the upper left and select your console’s tab and the relevant radio button for RGH 1.2.
 * 5) *You can use the timing assistant in the bottom left to auto select a safe timing for your motherboard revision.
 * 6) Click "Program". When complete, unplug the cable from the glitch chip.
 * 7) *Coolrunner: Set the switch back to "NOR".

X360ACE V4/V5/V3+

 * xFlasher or other Gowin compatible programmer required in order to program these chips
 * Programming Instructions

Decrypting the NAND

 * 1) Connect Ethernet and power on the console. The glitch chip should blink once or more times, and then the console should start into XeLL RELOADED.
 * 2) Once XeLL finishes, it will display your CPU key and some other info. There is also an IP address.
 * 3) Enter the IP address into the box on the lower right of J-Runner and click "Get CPU Key". J-Runner will pull the info from the box, and decrypt the NANDs automatically.

Writing New NAND Image

 * 1) Power down the console, and connect your programmer to the motherboard.
 * 2) *If you are using an xFlasher, ensure the switch is set to.
 * 3) In the upper right of J-Runner, ensure the  radio button is selected.
 * 4) * Enable  for better boot times.
 * 5) Click "Create XeBuild Image". This will take a few moments.
 * 6) Click "Write NAND".
 * 7) Disconnect your programmer when the process completes.
 * 8) Boot the console several times and ensure it boots consistently. If not, make sure your wiring is clean and neat and avoids noisy area. Run the wires near the X-Clamps for best results.
 * 9) Tune glitch chip timings if necessary.
 * 10) Return to the RGH main page and continue in the Cleaning Up section.

Jasper Consoles

 * If the console does not glitch reliably even after tuning the value, add 68nf-100nf capacitor (ex: 683 cap or SMD cap) from PLL to GND.
 * Onboard 100nf on Coolrunner Rev-C may be used by bridging CAP.
 * Onboard 100nf on Squirt Reloaded 2.X may be used by bridging J5.
 * If adding a cap, PLL will be more sensitive to noise. If you have strange blinking, be sure that your wire is routed away from clock signals.
 * For X360ACE/DGX make sure the capacitor is after the 22K Ohm resistor.

Tuning Glitch Chip Timings
Start at the top of the recommended range (noted in J-Runner's timing assistant) and work down until you get good boots. On chips with crystals, the optimal timing will depend on the crystal (how close it is to its rated frequency)

If the light stays on at the end of a cycle:
 * This means that the checks were passed, but the console failed to start
 * Probably the timing is too low, or the pulse length is too large

If the light goes off at the end of a cycle but doesn't boot:
 * This means that the checks failed
 * Probably the timing is too high, or the pulse length is too small

Note that the debug light behavior may be slightly misleading due to using POST_OUT bit 0.
