The longer you lasted before being destroyed, the further in the game you'll resume.

WIP:

- 6th August 2011: Guru - A couple of boards arrived for decapping. Slapfight A76 version and Return of the Invaders. Both have a 68705P5 MCU. Thanks to Tingoes for the donations.

- 6th June 2011: Guru - Some items arrived: Slap Fight very rare alternative version with A76 ROMs and A76 68705P5 MCU. Thanks to tingoes.

- 6th September 2010: Mr. Do - Alcon is done, thanks to Kiltron for cleaning, and to Zorg for sending in the bezel to be scanned.

- 0.138u3: Phil Bennett and Dr. Decapitator hooked up Slap Fight/Alcon 68705 MCU. Brian Troha and Guru corrected rom names for the Slap Fight sets, added PCB locations to any set where possible, added DIP locations and moved PCB information down to matching rom sets. Changed 'Alcon' to parent set 'Alcon (US)' and clones 'Slap Fight (Japan bootleg)' to 'Slap Fight (bootleg set 1)', 'Slap Fight (English bootleg)' to 'Slap Fight (bootleg set 2)', 'Slap Fight (bootleg)' to 'Slap Fight (bootleg set 3)', 'Slap Fight (set 1)' to 'Slap Fight (Japan set 1)' and 'Slap Fight (set 2)' to 'Slap Fight (Japan set 2)'. Renamed (slapbtjp) to (slapfighb1), (slapbtuk) to (slapfighb2) and (slapfgtr) to (slapfighb3).

- 25th June 2010: Guru - The 68705P5 MCU (A77_1) for Slap Fight has now been successfully processed (decap, de-protect & read).

- 0.133u1: Renamed (slapfiga) to (slapfigha).

- 0.123u1: Corrado Tomaselli corrected the clocks in Slap Fight. Changed Z80 CPU2 clock speed to 3MHz.

- 0.104u9: David Haywood added clone Slap Fight (set 2). Changed parent description to 'Slap Fight (set 1)'.

- 0.104u8: David Haywood added clone Slap Fight (bootleg).

- 24th March 2006: f205v dumped Slap Fight (bootleg).

- 12th September 2005: Guru - Slap Fight with a 68705 MCU arrived. Thanks to Tingoes.

- 16th April 2005: Guru - Alcon (with 68705P5, unfortunatley it's protected!) arrived. Thanks to the good boys at the Italian MAME Forum.

- 14th March 2005: Corrado Tomaselli dumped Slap Fight (set 2).

- 0.35: Changed description of clone 'Slap Fight (Japanese bootleg)' to '(Japan bootleg)'.

- 0.35RC1: Marco Cassili added clone Alcon. Not working due to protection.

- 0.34b4: Sebastien Chevalier improved music tempo in Slap Fight.

- 0.34b1: Christoff Feldtmann improved gfx in Slap Fight.

- 0.33b7: Keith Wilkins added accurate colors to Slap Fight. Renamed (slapboot) to (slapbtjp) and (slpboota) to (slapbtuk). Known issues: Scrolling is jerky. Music tempo is too slow.

- 0.33b2: Keith Wilkins added Slap Fight (Taito 1986) and clones (Japanese Bootleg) and (English Bootleg). Due to protection, the original version doesn't work. Scrolling is jerky. Music tempo is too slow. Use one of the bootlegs instead. The three games are identical, only the 1st CPU EPROM is different which shows up in the boot message, one if Japanese domestic and the other is English. The proms which MAY be the original slapfight ones currently give a hardware error and fail to boot.
