@ -18,13 +18,12 @@ How to set up the machine (motrshow, motrshowa, dakar):
- Press Left shift and Right shift together (game stops responding)
- Turn the Ram Protect Switch back on
- Press F3 or reboot
- The default settings have been loaded and you can insert coins
- The default settings have been saved to nvram and you can insert coins
- However, the game cannot be played due to missing balls.
ToDo:
- Support for electronic volume control
- Audio rom banking
- Wrong colours
- Most sounds missing due to unemulated M114 chip
- wcup90 is different hardware and there's no schematic
