- 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?
