Game notes...
The third set is resetting after drawing the maze, and when start a game.
Attract reset:
bp d28e (this is after all the jsr tables that draw the maze)
$d296: jsr $e0cd...
$e189 (jsr $6337) ; $6337 ---> Goes nowhere. Hit the 00's (BRK) and reset.
Start reset:
$e0e9: 4c ee 60 ; jmp $60ee <--- nothing here.

Petaco's 2-player game.
C1.bin was redumped from another board with the same set.
The original device was bitrotten. Each 0x1b offset (1b, 2b, 3b, etc)
has bit7 fixed to zero, in range 0000-026f.
The code executes subroutines located out of the ROM space.
Finally jumps to nowhere.
