Ground Effects is effectively a 30Hz game - though the vblank interrupts
still come in at 60Hz, the game uses a hardware frame counter to limit
itself to 30Hz (it only updates things like the video registers every
other vblank). There isn't enough cpu power in a 16MHz 68020 to run
other vblank). There isn't enough cpu power in a 20MHz 68020 to run
this game at 60Hz.
Ground Effects has a network mode - probably uses IRQ 6 and the unknown
