U.S. Championship V'ball (US) and M.A.M.E.
0.129u5 [Smitdogg]
0.37b12 [Paul Hampson]
Bugs:
- Sprites right offset with Flip Screen ON. Tafoid (ID 04986)
WIP:
- 0.146u2: Smitdogg and The Dumping Union added clone U.S. Championship V'ball (bootleg of Japan set). Changed description of clone '(bootleg)' to 'U.S. Championship V'ball (bootleg of US set)'.
- 0.143u1: Brian Troha added DIP locations to the U.S. Championship V'ball sets.
- 0.134u4: Fixed loading (vball) a second time from the MAME game selection screen corrupts the sprite colors.
- 0.130u3: Aaron Giles merged memory maps in U.S. Championship V'ball.
- 0.129u5: Smitdogg added U.S. Championship V'ball (US). Changed 'U.S. Championship V'ball (set 1)' to clone 'U.S. Championship V'ball (bootleg)'. Renamed (vball) to (vballb).
- 0.129: Mamesick converted the V'ball driver to use scanline interrupts, partial updates and raw video parameters. Changed visible area to 256x240 and VSync to 57.444853 Hz.
- 0.122u4: Bryan McPhail fixed slowdown in U.S. Championship V'ball.
- 0.77u3: Jarek Burczynski updated V'ball (Japan) to use graphics extracted from original PCB. Version (Japan) uses like (set 1) the gfx1 roms from a bootleg before. The (Japan) board has the image data stored in a special ceramic embedded package made by Toshiba with part number 'TOSHIBA TRJ-101', which has been dumped using a custom made adapter. There are a few bytes different between the bootleg and the original (the original is correct though!).
- 4th December 2003: Jarek Burczynski fixed the ROM names and background data in U.S. Championship V'ball (Japan).
- 12th September 2003: Guru - Finally completed the adapter to read the nasty Toshiba embedded ROM on US Championship V'Ball. Still some work to do though, it's not quite giving us the correct read yet... it's taken Jarek and I many hours over several months to get to this point, we're not far off now!
- 0.69u3: Guru corrected various clocks in the V'ball driver. Changed description of clone '(Japan bootleg)' to '(Japan)'. Changed M6502 CPU1 clock speed to 2MHz and MSM6295 to 8000 Hz.
- 25th May 2003: Guru - Received US Championship V'Ball (Technos 1988) from Japan. Thanks to Karasu Tojo.
- 0.67: Steve Ellenoff submitted various graphics emulation improvements to the U.S. Championship V'ball driver. Changed visible area to 240x240, scrolling, background tiles and dipswitches.
- 0.37b12: Paul Hampson added 'U.S. Championship V'ball (set 1)' (Technos 1988) and clone (Japan bootleg). TODO: Needs to be tilemapped. The background layer and sprite layer are identical to spdodgeb, except for the back-switched graphics roms and the size of the pallete banks. Someone needs to look at Naz's board, and see what PCM sound chips are present.
- 12th November 2000: Paul Hampson submitted an almost perfect US Championship V'Ball driver, only some sound problems remain.
