MAME Info:

0.59 [David Haywood]

Artwork available


- 0.136: Added eeprom-s1945ii.bin EEPROM.

- 3rd December 2006: Mr. Do - We have the instruction card for Strikers 1945 II from Hoppmann79.

- 0.63: Added 'Debug' dipswitch.

- 0.59: David Haywood added Strikers 1945 II (Psikyo 1997). Known issues: Game hangs on one of the bosses sometimes, core bug? Or something to do with unknown / incorrectly handled reads? Why does s1945ii boot as japan when the board was world? EEPROM value?

- 1st March 2002: R. Belmont fixed a bug in the SH-2 CPU core which fixes the missing background graphics in Strikers 1945 II, although they still aren't perfect due to other unemulated features.

- 22nd February 2002: David Haywood reported some more progress with the newer Psikyo games. Most color problems are fixed, Sol Divide also works and Daraku Tenshi - The Fallen Angels also works almost up to the actual game but crashes at that point. The background graphics in Strikers 1945 II and Space Bomber are still missing, though.

- 21st February 2002: David Haywood reported some progress in emulating Hitachi SH-2 based Psikyo games. Strikers 1945 II and Space Bomber are playable, although they miss a lot of graphics, have some wrong colors and no sound.

- 4th January 2002: Guru - Dumped Strikers 1945 II.

- 0.60: Added 'Region' dipswitch.

- 16th September 2001: Guru - Received Strikers 1945 II (Psikyo 1997). Thanks go to Smitdogg for the donations.
