WIP:
- 15th May 2011: Mr. Do - Everyone say hi to Mikonos, from Zona Arcade. In just the past week, he's already fixed up Gunforce bezel from the BYOAC / CAG artwork (scanned and provided). Hopefully, he plans to stick around for awhile.
- 0.133u1: Renamed (gunforcu) to (gunforceu) and (gunforcj) to (gunforcej).
- 16th November 2008: Guru - I recently picked up a pile of junk for spares and repairs from a local friend. It turned out there was quite a bit of interesting stuff in this lot. As far as I can make out, I got Gunforce (Irem).
- 0.104u8: Fixed rom names.
- 0.56: Added 'Unknown' dipswitch.
- 0.53: Bryan McPhail and Nicola Salmoria decrypted the sound CPU in Gunforce, Blade Master, Lethal Thunder, Undercover Cops, Mystic Riders, Major Title 2, Hook, R-Type Leo, In the Hunt and Perfect Soldiers.
- 18th July 2001: Nicola Salmoria fixed several NEC CPU core bugs and errors in the IREM CPU decryption tables, and got sound working in Gunforce.
- 0.37b8: Added clone 'Gunforce - Battle Fire Engulfed Terror Island (Japan)'. Bryan McPhail added preliminary Irem GA20 sound emulation. Preliminary sound in Blade Master, Gunforce, Undercover Cops and Lethal Thunder. Added V30 (14318180 Hz) CPU2, YM2151 (3579545 Hz), GA20 (3579545 Hz) and fixed gfx1/gfx2 rom addresses.
- 10th April 2000: Guru - Dumped Gun Force (Irem, Japan).
- 0.36b15: Added dipswitches 'Difficulty', 'Bonus Life', 'Allow Continue' and 'Demo Sounds'.
- 0.36b11: Changed description to 'Gunforce - Battle Fire Engulfed Terror Island (World)'.
- 3rd December 1999: Bryan McPhail sent in a M92 update with a few fixes to Gunforce and some speedups.
- 0.36b10: Changed description to 'Gunforce - Battle Fire Engulfed Terror Island input_ports_(World)'.
- 0.36b9: Bryan McPhail and Nao fixed a few bugs in the NEC CPU core that caused problems in Hook, Gunforce, Lethal Thunder and maybe others.
- 0.36b6: Bryan McPhail added Gunforce - Battle Fire Engulfed Terror Island (World) (Irem 1991) and clone (US). Known issues: Random crashes. Water doesn't appear on last(?) level. Waterfalls on level 3(?) should appear over sprites. Bit 0x8 in playfield 3 set - new type of split tilemap?
- 24th September 1999: Oliver Bergmann sent in a NEC V20, V30, V33 cpu core, and Bryan McPhail submitted an Irem M92 driver with support for Blade Master, Gunforce, Lethal Thunder, Hook, Undercover Cops, R-type Leo, Major Title 2 and In The Hunt, but none of the games have sound because of an encrypted sound CPU.
