Atari Seattle hardware

There are 2 types of California Speed, one of which does not utilise the 4 position shift lever. This was the factory kit that converted "Hyperdrive" to California Speed.

Release 1 :

* version 1.0r7a (3/4/98)

Release 2 :

* version 2.1a (4/17/98)


* Bonus Cars : Set your transmission number to 1, then press RADIO in the car selection screen to change one car from each row into a different vehicle.

* Fruit Attack : If you get ahead of someone tap your gas pedal and the START button simultaneously to throw fruit at the driver behind you. This is pointless but fun.

* Mirrored tracks : hold down all 3 view buttons during track select for mirrored tracks.

* Backrow vehicles : press Tailgate Cam button during car select to choose backrow vehicles.

* During attract mode, press View 1+View 3+Radio to see the version/revision of your machine.

MAME Info:

0.102u5 [Reznor007]

0.77 [Aaron Giles]

HardDisk required


- Incorrect alpha in Mt. Shasta stage on 64-bit build. AWJ (ID 04157)

- Even if you choose manual gear your car has automatic gear. Scagazza (ID 00975)

- Clone calspeda: After the calibration screen the game remains in black screen state. Scagazza (ID 00977)


- 0.133u1: Renamed (calspeda) to (calspeeda).

- 0.126u2: Aaron Giles fixed refreshspeed causes horrible screetching.

- 0.102u5: Reznor007 added 'California Speed (Version 2.1a, 4/17/98)'. Changed parent description to 'California Speed (Version 1.0r7a 3/4/98)'. Renamed (calspeed) to (calspeda).

- 0.82u2: Aaron Giles formalized support for the "widget" board used in Vapor TRX & California Speed, added more extensive documentation on the various boardsets, constants for the GT64010 and all interrupts and ethernet device interrupt support. Made the IDE controller visible on the PCI bus, hooked up CMOS protection bit, corrected 'San Francisco Rush: The Rock' audio CRCs and hooked up hard disk and marked San Francisco Rush and Vapor TRX as working.

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

- 0.78u4: Changed region cpu2 to sound1.

- 0.78: Aaron Giles fixed remaining issues in California Speed, verified California Speed HDD dump (works in self test, not in boot ROM test) and changed year to 1998 - Game now playable.

- 0.77u3: Aaron Giles fixed several minor bugs that affected Biofreaks and California Speed. Fixed input ports for California Speed and SF Rush. Changed visible area to 512x400. Removed Player 3/4 and button 6. Added 'Boot ROM Test' dipswitch.

- 7th December 2003: Aaron Giles fixed several minor bugs in the Seattle driver that affected Biofreaks and California Speed (but they're still not fully working).

- 2nd December 2003: Aaron Giles - Well, I finally decided to figure out what the heck was up with California Speed. Turns out there were a few subtle problems in the PCI configuration code when setting up the 3dfx card. With that fixed, I was able to map the proper self-test button, and finally hook up all the controls. Then came some ugly sound synchronization issues. Like Wayne Gretzky's 3D Hockey, this game won't boot unless the sound is working. After some fiddling, I was able to get it to work. Unlike San Francisco Rush, this one starts up and is playable, though there are some obvious color issues (well, not so obvious here, but it is in other screen shots). However, it doesn't last too long until we hit a snag. Much like San Francisco Rush, we get some math errors and the game freaks out. I really hope this doesn't mean I have to add full floating point exception support...

- 0.77u2: Added cpu2 sound rom (32k ADSP2115 data) and changed R5000 CPU1 clock speed to 150 MHz.

- 0.77: Aaron Giles added California Speed (Atari 1996). Doesn't boot, will go into test mode (bad hard disk dump).

- 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.
