I have somehow gotten Mirada 1997 firmware on this thing, along with Generic 118, Gamemate 2000, Gamemate 8888 and Gamemate 9999, all accessible on the same brick game.
They all have tetris too, which it didn’t have before.
Most of the firmwares are unfortunately broken, except for Generic 118 which works just fine.
All of the Gamemate firmwares have both broken screen layout and broken controls.
Mirada firmware only has broken controls, the screen is working fine.
I’m probably gonna keep it like this from now on, because it has more games than the original 5000 firmware.
