MAME Info:

0.18 [Nicola Salmoria, Mirko Buffoni]


- 0.122u7: Changed NSC8105 CPU2 clock speed to 6MHz.

- 0.106u12: MASH added pld ($0 - pal16h2.3b) to Seicross and clone Sector Zone.

- 0.78u5: Stefan Jokisch fixed DIPs in Seicross. Added dipswitches 'Difficulty', 'Bonus Life' and 'Invulnerability'. Removed 3rd coin slot.

- 30th November 1999: Zsolt Vasvari sent in a NSC8105 core and modified Seicross driver to use it.

- 0.36b11: Replaced M6802 CPU2 with NSC8105.

- 0.35b12: Changed M6802 CPU2 clock speed to 1.5MHz.

- 0.35b10: Replaced M6808 CPU2 with M6802 (6MHz).

- 0.35b6: Replaced M6803 CPU2 with M6808.

- 0.35b2: Nicola Salmoria emulated the protection in Seicross. Added M6803 (3072000 Hz) CPU2 and DAC sound.

- 0.35b1: Nicola Salmoria added clone Sector Zone. Fixed rom names.

- 0.34b1: Added color proms ($0, 20).

- 0.31: Known issues: Doesn't work well; for example, you always start with 99 lives, and coins are only accepted from coin C (default key: 5). It looks like there is a microcontroller on board, which is not emulated.

- 0.29: Accurate colors in Seicross [Tim Lindquist, Nicola Salmoria].

- 0.24: In Seicross now shots are enabled. Control: Arrows = Move around and CTRL = Fire (if SW7B is enabled). REMEMBER TO DELETE PREVIOUS .DSW FILE, AND SET "DEMO & DEBUG MODE" TO OFF, AND "SW7B" to 1. Setting SW7B to 0 will cause to play the game without FIRE facility. Changed description to 'seicross'.

- 0.23: Mirko Buffoni fixed Seicross which is now playable and has music too. REMEMBER TO DELETE PREVIOUS .DSW FILE, AND SET "DEMO & DEBUG MODE" TO OFF. Control: Arrows = Move around. Known issues: You must remember to setup "Debug and Demo" mode to OFF. Colors are wrong.

- 0.18: Preliminary support for Seicross (Nichibutsu + Alice 1984), using the Crazy Kong driver. Not playable. Runs on almost the same hardware as Crazy Climber, but not exactly the same.
