lr- Atari800 - Screen issue for Adafruit PiTFT Plus 320x240 3.2" TFT
I don't know if It's RetroArch or my screen with this emulator but when I start a game with Ir-atari800 , the screen is like this (for Atari800, 5200, etc). I got all BIOS, I set the good system in retroarch, I have tried everything (all screens setups) before the game is loading and nothing works. All emulators on Retropie work on that screen except lr-atari800.
Working video mode for others emulators and the picture on that post : 320x240 @ 59Hz 4:3, clock: 24MHz x4
Note: The games are loading and working. It's seems to be only an visual issue.
Is It because It only supports 720P?
SOLVED: In Retroach, internal resolution must be 336 x 240 !
Just good to know
