Probably tracing pin connections to the HX881 will confirm it.
You can switch the games pulsing their respective hidden buttons.
Hidden Switch:
Unknown, yet...
You can enter Cherry Master mode in same way like other Tetris versions.
One wire goes to edge connector 35 + 36 (solder side), putting PPI (u34)
pin 14 (PC0) to GND (needed to get the switch working).
One button adds GND to the edge connector 8 (solder side):
PPI pin 18 (PB0), to switch to Tetris game.
The other button, adds GND to the edge connector 7 (solder side):
PPI pin 19 (PB1), to switch to Cherry Master game.
Need proper implementation.
