MAME Info:

0.30 [Lee Taylor, John Clegg]

Artwork available (motorace)


- 0.140u2: Atari Ace take some driver_device classes of m52/m57/m58/m62/travrusa (common code in audio/irem.c) that cover multiple drivers and split them so that each driver gets their own driver_device class. In most cases, these drivers got entangled because of audio/mcu code that was shared between multiple drivers. Added 'Irem Audio' sound.

- 7th December 2009: Mr. Do - Thanks to some great photos as Derek's Basement Arcade, I added in instruction cards to the bezels for Motorace USA.

- 0.135u1: Fabio Priuli added driver data struct and save state support to Traverse USA driver.

- 7th August 2009: Smitdogg - Thanks to D. Beneke we got a box of PCB's from a dealer in NY for pretty cheap. I've dumped all. One is a Zippy Race bootleg.

- 0.133u1: Improved Irem sound [Couriersud]: Revisited schematics. Corrected a bug, some discrete values and added two RC nodes from schematics.

- 26th July 2008: Mr. Do - Thanks to the BYOAC/CAG artwork, we now have a MotoRace USA bezel.

- 0.123u2: Fixed proms addresses from ($100, 120) to ($200, 220). Changed palettesize to 256 colors.

- 0.124u5: Couriersud added discrete mixing and filtering to IREM games using M52-sound-c boards: Moon Patrol and Traverse USA. Replaced 2nd MSM5205 sound with Discrete.

- 0.122u8: Fixed cpu2 rom address to $7000.

- 0.122u7: Changed M6803 CPU2 clock speed to 3579545 Hz.

- 0.106u12: Fixed rom names.

- 0.64: Changed VSync to 56.75 Hz and palettesize to 144 colors.

- 0.37b6: Changed M6803 CPU2 and the 2x AY-8910 clock speeds to 894886 Hz.

- 0.35b11: Changed M6803 CPU2 clock speed to 1.5MHz.

- 0.35b10: Changed M6803 CPU2 clock speed to 6MHz.

- 4th March 1999: Nicola Salmoria has converted Traverse USA to the tilemap system for testing purposes.

- 0.35b5: Nicola Salmoria kludged in a fix for char/sprite priority in Traverse USA. The TileMap code is now mature enough to be used in new drivers. For examples, look into gng, gaiden and travrusa [Phil Stroffolino].

- 0.35b3: Changed M6803 CPU1 clock speed to 1MHz. Added 2nd player input and a 3rd coin slot.

- 0.35b1: Changed description to 'Traverse USA / Zippy Race'.

- 0.34RC1: Nicola fixed music in Traverse USA.

- 0.34b1: Added color proms ($0, 100, 120 - character, sprite and lookup table).

- 0.33b4: Nicola Salmoria added clone MotoRace USA. Known issues: Hanging note at the beginning of the race.

- 0.31: Gerald Vanderick added accurate colors to Traverse USA.

- 0.30: Lee Taylor and John Clegg added Traverse USA (Irem 1983) and clone Motorace USA (Testdriver). Need color proms.

- 14th November 1997: Thierry and Gerald dumped Traverse USA / Zippy Race Irem Corp, 1983.
