- sf2ub: Original PCB running attract mode through an RGB board and into my PC. Smitdogg (ID 04003)


- 0.151: ANY and The Dumping Union added clone Street Fighter II: The World Warrior (World 910318).

- 0.150: Tormod, Layne, Smitdogg and The Dumping Union added clone Street Fighter II: The World Warrior (Japan 920312). Yohji, Kevin Eshbach, bodger319, Smitdogg and The Dumping Union added clone Street Fighter II: The World Warrior (Japan 910522). Kevin Eshbach, Bill D., Layne, Smitdogg and The Dumping Union added clone Street Fighter II: The World Warrior (Japan 910411).

- 29th August 2013: Smitdogg - I got another undumped Street Fighter II, 910411 Japan.

- 13th August 2013: Smitdogg - We got another undumped Street Fighter 2 board, 910522 Japan.

- 12th August 2013: Smitdogg - Andrew Welburn dumped a bootleg of Street Fighter 2.

- 6th August 2013: Smitdogg - I just got the best version ever made of Street Fighter 2 World Warrior. Why is it the best you ask. It's the final Japanese revision completed one day before the first version of Champion Edition was released (920312). So they were working on final updates for World Warrior at the same time they were making Champion Edition. It looks like nobody I know even knew about it until now. Until we found this I had never even heard of a World Warrior made past summer 1991 let alone the day before the first Champion Edition in 1992. So it should be the most bug free and tweaked out and also being the Japan version, the AI is going to be more pure and not quarter sucking.

- 0.148u1: Team CPS-1 confirmed 1 label in clone Street Fighter II: The World Warrior (USA 910228) according to the real board.

- 0.147u4: Changed description of clones '(TAB Austria, bootleg) (set 1)' to 'Street Fighter II: The World Warrior (TAB Austria, bootleg, set 1)', '(TAB Austria, bootleg) (set 2)' to 'Street Fighter II: The World Warrior (TAB Austria, bootleg, set 2)' and '(unknown bootleg)' to 'Street Fighter II: The World Warrior (RK, bootleg)'. Renamed (sf2unkb) to (sf2rk).

- 0.147u3: Darran, Smitdogg and The Dumping Union added clones 'Street Fighter II: The World Warrior (TAB Austria, bootleg) (set 2)' and 'Street Fighter II: The World Warrior (unknown bootleg)'. Added some non-working Street Fighter 2 bootlegs, the PCBs are broken and missing roms so they're just for reference [ReadOnly]. Changed description of clone '(TAB Austria, bootleg)' to 'Street Fighter II: The World Warrior (TAB Austria, bootleg) (set 1)'.

- 0.145u4: Bonky0013 and JacKc added clone Street Fighter II: The World Warrior (USA 910522, Rev. G). Fix for copy/paste error in clone (USA 910522, Rev. G) [Tafoid]. Changed description of clone '(USA 910522)' to '(USA 910522, Rev. I)'.

- 0.144u3: Added missing pld ($0 - stf29.1a).

- 0.140u2: Layne, Smitdogg and The Dumping Union (Team CPS-1) added clone Street Fighter II: The World Warrior (World 910228).

- 0.139u2: Team CPS-1 fixed labels in clone 'Street Fighter II: The World Warrior (USA 910206)' and added PCB infos

- 18th August 2010: Smitdogg - I got a box from Dave France with some donations and loaners. First is a Street Fighter 2 set. It had bad graphics. I swapped the motherboard with a spare I had and it works perfectly. I'll get the missing PAL dumped from it.

- 11th August 2010: Smitdogg - A non-working SF2 board set arrived thanks to john666 to fix a set in MAME and check for possible revision.

- 0.139: Changed description to 'Street Fighter II: The World Warrior'.

- 0.137u4: Smitdogg and The Dumping Union added clone Street Fighter II - The World Warrior (Thunder Edition).

- 28th April 2010: Smitdogg - I got another rare Street Fighter 2 bootleg called Thunder Edition. It uses a custom PAL for protection which Phil B. will likely crack in 6-7 seconds. The rom stickers were mostly destroyed so I printed it some fresh ones. The giant plastic sticker over the MASK roms came like that though.

- 18th September 2009: Smitdogg - I got 2 of the remaining undumped Street Fighter 2 kitted bootlegs. I picked up a Street Fighter 2 Quicken Pt.1 board. The Quicken boards supposedly came out before the official Champion Edition, Turbo, etc. and are rumored to have been responsible for "inspiring" Capcom to make the Champion Editions etc. in order to compete with the bootleggers. I've been wanting these for a while, they are fairly important as far as bootlegs go. I've bid on them before but they always sold for too much, but this time I got nice prices.

- 0.129u1: Phil Bennett fixed scrambled graphics in clone (US 910228).

- 0.126u5: Added A-board PLDs (buf1, ioa1, prg1, rom1 and sou1).

- 0.124u4: Lowered SF2 clock speed to 10MHz. This is on the assumption that, since the 12MHz A-Board is called "89626A-4 DASH", it should have started to be used with SF2 DASH--that is, sf2ce [Nicola Salmoria, Corrado Tomaselli, Charles MacDonald].

- 8th October 2006: Mr. Do - Added the instruction sticker for Street Fighter II, thanks to Tormod.

- 18th September 2006: Mr. Do - Added Street Fighter II bezel, thanks to Terry Terry Roberts.

- 21st February 2001: Nicola Salmoria added buffering to the keyboard input code, allowing more than two keypresses at the same time. This fixes Zangief's spin in Street Fighter 2.

Restored back the rom parts removed in previous updates because they needed to be documented and added the missing ones of the recently dumped 3wondersr1.

- 0.148u1: Added machine\kabuki.h. CPS1 modernisation. Splitted kabuki (decoding functions) from cps1.h [Robbbert].

- 18th August 2010: Smitdogg - The box of Capcom goodies arrived today from Japan. They are Japanese versions of Knights of the Round, Willow, and King of Dragons. In Willow's case we got it to correct the current set using incorrect roms. But for the other 2, yet again, the program rom labels indicated new versions we don't have dumped and so far look to be matching currently dumped sets, or at least doing some mixmatching with program roms and different sizes on graphics roms. I'm not really sure yet to be honest, they aren't fully dumped yet. You'll see why when you see how many roms they use. I'll finish dumping them all tomorrow.

- 10th August 2010: Smitdogg - We won the Capcom games that I was raising money for a few days ago. They should arrive in about a week. There is other oldschool Capcom news on the way as well.

- 0.129u4: Nicola Salmoria fixed a contact MAMEDEV messasfbonus.cge in the CPS1 driver.

- 0.128u4: Updated CPS1 documentation [Nicola Salmoria].

- 0.127u1: Additional input port cleanups in the CPS1 driver [Fabio Priuli].

- 0.127: Nicola Salmoria updated CPS1 to use proper gfx ROMs (+ PALs) for Varth (Japan 920714), and to load correct A-Board PALs for QSound games.

- 0.126u5: Corrado Tomaselli and Charles MacDonald added reverse engineered PLD images to CPS1 games (A-board to all and B-board and C-board to many).

- 0.126u4: Corrado Tomaselli verified and corrected CPS1 refresh rate. Changed VSync to 59.610000 Hz.

- 0.125u6: Corrado Tomaselli changed all games after Street Fighter 2 CE to have a 12MHz clock. Verified on Mega Man and Quiz & Dragons (original kits with plastic case). I am resonably sure all the other games after ST2CE have the DASH CPS1 board with 12MHz clock.

- 0.125u3: David Haywood fixed duplicate input port bits in CPS1 driver.

- 0.124u5: Massive update to ROM naming in the CPS1 driver, also loading smaller EPROMs for Japanese sets instead of the larger mask ROMs where possible. Added information about B-Board revisions where possible. There is still work to do on this regard but this is a first step in untangling the mess [Nicola Salmoria]. Nicola Salmoria and Corrado Tomaselli verified more CPS1 gfx ROM mappings against PALs. Fixed rom names in all games.

- 0.124u4: Further CPS1 improvements [Nicola Salmoria, Corrado Tomaselli, Charles MacDonald]: Fixed layer enable at the end of stage 4 in Varth. Increased Varth CPU clock to 12MHz to reduce slowdowns (the game was released after sf2ce so the faster A-board was available). Verified more gfx rom mappings against PAL dumps (thanks to Corrado). Verified memory maps using A-board PAL dumps (thanks to Charles). Separated the address ranges for CPS-A and CPS-B customs. This finally clarifies why some registers are fixed and some change with every game. Identified three new unknown registers in the CPS-B-21 custom. Their purpose is unknown. All unhandled accesses to CPS-A/CPS-B registers will now be reported. There shouldn't be any left. Look out for "contact MAMEDEV" popups. Cleaned memory maps. Moved Forgotten Worlds special input memory handlers to DRIVER_INIT. Moved extra input handlers to video\cps1.c since the extra connectors are on the C-board. Added sound to Final Crash. Lowered SF2 clock speed to 10MHz. This is on the assumption that, since the 12MHz A-Board is called "89626A-4 DASH", it should have started to be used with SF2 DASH--that is, sf2ce.

- 0.124u3: Nicola Salmoria and Corrado Tomaselli fixed CPS1 palette control register to match tests on Magic Sword PCB. Nicola Salmoria verified several CPS1 graphics ROM mappings against PAL dumps. Nicola Salmoria merged CPS1, CPS2 memory maps and some tweaks from schematics, though to get perfect memory maps dumps of the A-board PALs would be needed.

- 0.124u2: Verified some CPS-1 GFX rom mapping tables against PAL dumps. Improved understanding and emulation of palette related registers [Nicola Salmoria, Corrado Tomaselli]. Nicola Salmoria removed CPS1 tile kludges and replaced with per-game ROM mapping tables. Ideally, the ROM mapping should be derived from mapping of the PALs found on the B board. Note that this is a significant change and some new bugs might be caused by it. Unlike previous bugs, where extra garbage tiles would appear in the games, the new bugs would be tiles or sprites MISSING--so they will be harder to notice. This would happen because in some cases the 16x16 regions of the gfx ROMs can be used by both scroll2 and sprites, while in other cases they must be separated.

- 0.124u1: Nicola Salmoria fixed CPS1 background color. This fixes 3wonders (game start) and mtwins (explosion during attract). It seems to break Varth, however, and has dubious effects on the boot sscreens of avsp, sfa3 and possibly other CPS2 games. Changed palettesize to 3072 colors.

- 0.122u8: David Haywood fixed the CPS driver to at least display the correct clock in the driver info, by degrading the clock through alternate means.

- 0.114: Aaron Giles fixed MAME crashed if you do a hardware reset in CPS-1.

- 0.112u3: MAME Italia forum connected brightness support on the CPS1 board (not just CPS2) after verifying that the real board does support it.

- 0.109: Input port cleanup and additional comments in the CPS1 driver [Stephane Humbert].

- 0.105u1: David Haywood updated CPS-1 driver to more accurately draw tilemaps, based on evidence from a board with mixed ROMs.

- 5th April 2006: David Haywood - A guy called Murray posted on the and forums about a problem he was having with his Final Fight PCB. The problem looked like it might be due to a mix of Japanese and US roms as the Japanese roms don't contain a full Winners Don't Use Drugs Logo. He got a friend to dump the socketed roms on the PCB and sure enough the socketed graphic roms matched the Japanese set in MAME. This set, being a newer US revision was then plugged into MAME (ffightua in .105) but there was something wrong. MAME displayed the Winners Don't Use Drugs screen perfectly with this mixed set of roms. At this point I wondered if maybe one or both of his Mask Roms were also from a Japanese revision so I loaded the US set with an entire set of Japanese GFX. The logo was broken, but not in the same way as the PCB. For a while this was rather confusing, it must be getting the Japanese characters from somewhere, but the only place they exist are in the Japanese roms, and it would appear the text layer graphics aren't used in them when running the US set. No matter what I tried to change in terms of the roms I couldn't reproduce the exact problem shown. Then I remembered, MAME had some code to force the 8x8 text layer characters to always be drawn from the Left Hand Side of each 16x16 tile (apparently for Carrier Air Wing...) but the left and right sides of almost every 16x16 character used for the 8x8 layer were identical. The screenshot made it quite obvious that the real hardware does not always draw the left hand side of the tile, but instead alternates from left side to right side for every column on the display. By implementing this behavior in MAME I was able to reproduce the same glitch shown on the real PCB when mixed roms are used. I suspect the problem with Carrier Air Wing which resulted in the left hand side always being used is another problem, the CPS video hardware is full of strange little hacks for the early CPS games anyway. The change will hopefully be in 105u1, I can't see anything broken by it, but some testing would be helpful.
