MOLE ATTACK by Yachiyo Electronics Co.,LTD. 1982
Known Clones:
"Holey Moley", from tai (Thomas Automatics, Inc.)
Known Issues:
- some dips not mapped
- protection isn't fully understood, but game seems to be ok.
- cpu speeds unverified
Buttons are laid out as follows:
7 8 9
4 5 6
1 2 3
Working RAM notes:
0x2e0 number of credits
0x2F1 coin up trigger
0x2F2 round counter
0x2F3 flag value
0x2FD hammer aim for attract mode
0x2E1-E2 high score
0x2ED-EE score
0x301-309 presence and height of mole in each hole, from bottom left
0x30a
0x32E-336 if a hammer is above a mole. (Not the same as collision)
0x337 dip switch related
0x338 dip switch related
0x340 hammer control: manual=0; auto=1
0x34C round point 10s.
0x34D which bonus round pattern to use for moles.
0x349 button pressed (0..8 / 0xff)
0x350 number of players
0x351 irq-related
0x361
0x362
0x363
0x364
0x366 mirrors tile bank
0x36B controls which player is playing. (1 == player 2);
0x3DC affects mole popmessage
0x3E5 round point/passing point control?
0x3E7 round point/passing point control?
