- TRIVIA -
It's a very rare prototype, there are only 2 or 3 in existence. The concept was just a little too hard for a mass market. It would make a great game, but Atari never decided to do anything with it. Its earnings in an arcade test just weren't high enough to justify production.

MAME Info:
0.36b7 [Aaron Giles]
WIP:
- 0.143u4: Changed 68000 CPU1 clock speed to 14318181 Hz.
- 0.141u4: Breaks some driver entanglements to simplify future driver_device conversion efforts [Atari Ace]: Arcade Classics driver is separated from Rampart by duplicating the bitmap rendering code.
- 0.129u1: MooglyGuy added savestate support to Sparkz.
- 0.125u1: Stephane Humbert renamed ports, used AM_READ_PORT macros and fixed Service Key was mapped twice in Arcade Classics.
- 0.114u2: Aaron Giles and Couriersud added more accurate video timing to most of the Atari 68000-era games. The parameters are from published specs, not derived. The board uses an SOS-2 chip to generate video signals. Changed VSync to 59.922743 Hz.
- 0.114: Couriersud added general save state support to the atarigen module.
- 0.36RC1: Changed 68000 CPU1 clock speed to 14318180 Hz and OKI6295 to 7231 Hz.
- 0.36b7: Atari Games added Sparkz (prototype) (Atari Games 1992).
- 13th October 1999: Aaron Giles sent in drivers for two Atari prototype games: Arcade Classics and Sparkz.
