0.36b1 [Aaron Giles]

WIP:
- 0.143u4: Changed 68000 CPU1 clock speed to 14318181 Hz.
- 0.139u1: Aaron Giles changed atarigen_state to be a base class from which all the related Atari drivers derive their state from.
- 0.135u4: Some more Atari driver shuffling [Aaron Giles]: Added atarigen_init() function which allocates all timers and registers for save states. Updated all drivers to call it. Converted some drivers to use device timers.
- 0.135u3: Aaron Giles converted atari drivers over to using driver_data for the most part. Some shared systems still exist with globals, but this tackles the atarigen module and the variables local to each driver.
- 0.125u7: Aaron Giles fixed 'Fatal Exception' crash.
- 0.122u4: Changed M6502 CPU2 clock speed to 1789772 Hz, YM2151 to 3579545 Hz and OKI6295 to 1193181 Hz.
- 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. Changed VSync to 59.922743 Hz.
- 0.114: Couriersud added general save state support to the atarijsa and atarigen modules.
- 0.109: Canim removed 3rd coin slot from Hydra.
- 0.105u4: Fixed rom names.
- 0.86u4: Pierpaolo Prazzoli fixed broken controls in Hydra.
- 0.79u2: Changed Custom sound to DMA-driven_DAC.

- 6th February 2004: Aaron Giles fixed the recently introduced errors in Hydra, Pit Fighter and Escape Kids.
- 0.77: Aaron Giles added support for the MO command register (MO checksums now work). Added missing SHA1 values and marked some ROMs as NO_DUMP. Removed 6502 speedups.
- 0.68: Aaron Giles added clone Hydra (prototype 5/25/90). Changed description of clone '(prototype)' to '(prototype 5/14/90)'.
- 15th May 2003: Aaron Giles added another prototype of Hydra to the Atari G1 driver.
- 0.66: Added proms ($0, 200, 400 - Microcode for growth renderer).
- 16th February 2003: Aaron Giles added the proper microcode PROMs for the growth object generator in the Atari G1 and G42 drivers, and improved the SLOOP protection emulation in Road Riot, but it's still not playable.
- 0.37b15: Changed M6502 CPU2 clock speed to 1789500, YM2151 to 3579000 and OKI6295 to 9037 Hz.
- 6th April 2001: Aaron Giles fixed a bug in Hydra and Pit Fighter, which caused crashes in MAME32.
- 0.37b8: Changed palettesize from 1024 to 1280 colors.
- 0.36RC1: Changed 68000 CPU1 clock speed to 14318180 Hz, M6502 to 1789772 Hz, YM2151 to 3579545 Hz and OKI6295 to 9039 Hz.
- 0.36b2: Aaron Giles added clone Hydra (prototype) (Atari Games 1990).
- 0.36b1: Aaron Giles added Hydra (Atari Games 1990).
