additional information
info 0.36b1 [Bryan McPhail]

Bugs:
  • In attract mode, only for a frame, there's a sprite misplacement. timesold0123u1gre Robiza (ID 01428)
WIP:
  • 0.97u1: Pierpaolo Prazzoli added clone Battle Field (bootleg).
  • 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.
  • 0.36b16: 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.
