MAME Info:

0.36b1 [Bryan McPhail]


Bugs:

- In attract mode, only for a frame, there's a sprite misplacement. Robiza (ID 01428)


WIP:

- 0.140u2: Stephane Humbert fixed coins are not reacting correctly (MCU problem) in Time Soldiers and clones.

- 0.138u2: SftiKDL0 fixed input in Time Soldiers and clones (DIAL was used instead of rotary joystick).

- 0.133u1: Brian Troha added DIP locations to Time Soldiers. Renamed (timesol1) to (timesold1) and (btlfildb) to (btlfieldb).

- 0.130u4: Derrick Renaud converted Time Soldiers use IPT_POSITIONAL.

- 0.128u6: Phil Bennett reduced all Alpha68k YM2413 clocks from 8MHz to 3.579545MHz.

- 0.97u1: Pierpaolo Prazzoli added clone Battle Field (bootleg).

- 4th June 2005: Corrado Tomaselli dumped Battle Field (bootleg).

- 0.61: Changed 'Unknown' to 'Unused' dipswitch.

- 0.59: Acho A. Tang fixed priority in Time Soldiers.

- 18th March 2002: Acho A. Tang submitted a massive update for the Alpha68k driver, fixing a few graphics problems in Sky Adventure and Time Soldiers, and making Paddle Mania, Super Stingray and Kyros playable.

- 0.37b2: Changed description to 'Time Soldiers (US Rev 3)' and clones '(Rev 1)' to '(US Rev 1)' and 'Battlefield (Japan)' to 'Battle Field (Japan)'.

- 0.36b16: Renamed (timesol2) to (timesol1).

- 0.36b1: Bryan McPhail added Time Soldiers (Rev 3) (SNK / Romstar 1987) and clones (Rev 1) and Battlefield (Japan). The Time Soldiers title screen is corrupt when set to 'Japanese language', the real board does this too! Make the Time Soldiers ROM writable and the game will enter a 'debug' kind of mode, probably from the development system used.

- 17th July 1999: Bryan McPhail sent in drivers for Time Soldiers, Sky Soldiers, Sky Adventure and Gang Wars.

- 6th June 1999: Bryan McPhail has gotten a nice new shiny computer science degree, and for a nice celebration he almost finished some drivers. Here are some pics of Gang Wars, Gold Medalist, Sky Adventure, Sky Soldiers and Time Soldiers, but don't expect to see these before 0.36b1.
