MAME Info:

0.77 [Aaron Giles]

Artwork available

HardDisk required


- 7th December 2009: Mr. Do - Here is NFL Blitz '99 artwork that I had completed some time ago, but never got around to adding them in.

- 31st May 2009: Smitdogg - We got an update kit for Blitz '99 that, from the auction, looked to be a boot rom update. After receiving it, it looks like it is a kit to update the hard drive from 1.2 to 1.3, and thus not needed, but maybe it will come in handy somehow.

- 0.81u6: Aaron Giles fixed incorrect sound pitch in Blitz 99/2k.

- 0.79u2: Replaced Custom sound with 2x DMA-driven DACs.

- 0.78u4: Changed region cpu2 to sound1.

- 0.77u3: Changed ADSP2115 CPU2 clock speed to 16MHz and visible area to 512x400. Added dipswitches 'Graphics Mode' and 'Graphics Speed'.

- 0.77u2: Changed R5000 CPU1 clock speed to 150MHz.

- 0.77: Aaron Giles added NFL Blitz '99 (Midway 1998). No sound during movies (FIFO?). Random black frames.

- 5th November 2003: Aaron Giles sent in the Atari Seattle driver, supporting CarnEvil, Blitz 99, Wayne Gretzky's 3D Hockey, Mace: The Dark Age (all working fine) and San Francisco Rush (freezes when starting a game).

- 27th May 2003: Aaron Giles updated the IDE controller emulation to support a couple more commands and added DMA bus mastering support that will be necessary for the Seattle games.
