MAME Info:
0.91u1 [Aaron Giles]
HardDisk required
WIP:
- 0.103u3: Changed ADSP2104 CPU2 clock speed to 16MHz. Removed 4x DMA-driven DAC sounds and fixed dipswitches.
- 16th January 2006: Aaron Giles - Took a decent amount of hacking, but I'm finally into the attract mode in NBA Showtime. The game crashes out pretty quickly and there are other problems, but at least now I can verify that the CHD dump is good (and it is).
- 0.91u1: Aaron Giles added 'NBA Showtime / NFL Blitz 2000' (Midway 1999).
