0.153 [System11]

0.54 [Bryan McPhail, Nicola Salmoria]

0.36b7 [Testdriver]


WIP:

- 0.153: System11 added Air Assault (World). Improved sound cpu decryption by cross referencing code between sets, marked as working [David Haywood]. Correct w46 gfx1 rom name in Air Assault and standardized rom locations between parent & clone. Document the Air Assault encrypted sound CPU (NANAO 08J27261A1). IE: Confirms it's the same as Gunforce [Brian Troha].

- 0.146u3: Tafoid flagged Fire Barrel (Japan) as GAME_NO_COCKTAIL due to never having working flip screen.

- 0.144u5: Alex Jackson fixed music randomly blocks.

- 0.141u1: Changed V35 CPU2 clock speed to 14318000 Hz.

- 0.140u3: Angelo Salese added reset line trigger from main to sound CPU in Irem M107 driver, fixing Fire Barrel sound. Also added a preliminary hook-up for an alternative rowscroll effect in Irem M107 HW, noticeable in Fire Barrel stage 2 and 6. Angelo Salese and David Haywood added preliminary row select effect in Irem M107, fixes for good the start-up transitioning in Fire Barrel. Angelo Salese ported row select to every other tilemap in Irem M107 and fixed a bug in it, gives correct stretching gfxs at the end of level 1 and at the start of level 8 in Fire Barrel. David Haywood fixed rowscroll effect in Fire Barrel. Angelo Salese fixed a misplaced sprite bug in Fire Barrel. Angelo Salese and David Haywood fixed sprite-sprite priorities and a sprite sticking bug on game over screen in Fire Barrel. Angelo Salese fixed extensive issues with tilemaps/sprites. Changed input from 2 to 3 buttons. Added 'Rapid Fire' dipswitch.

- 0.129u5: Chris Hardy decrypted new opcodes for Fire Barrel. Angelo Salese fixed regressed rowscroll effect for Fire Barrel.

- 0.118: Fixed rom names.

- 0.66: Changed V33 CPU1 clock speed to 14MHz and V30 CPU2 to 7159000 Hz.

- 0.56: Added dipswitches 'Lives', 'Continuous Play' and 'Unknown'.

- 0.54: Bryan McPhail and Nicola Salmoria added 'Fire Barrel (Japan)' (Irem 1993).

- 13th August 2001: Nicola Salmoria attempted to add sound to Fire Barrel, but it doesn't work yet due to main CPU problems.

- 12th August 2001: Nicola Salmoria fixed the sprites in Fire Barrel making it more or less playable (tilemap scrolling problems remain).

- 0.36b7: Bryan McPhail added (Testdriver) Fire Barrel (Japan). Fire Barrel sprite indexes are wrong - encryption? There are two unused roms next to the sprite roms. Graphics glitches.

- 29th September 1999: Bryan McPhail sent a M107 driver with support for Fire Barrel (bad graphics) and Dream Soccer 94 (random crashes).
