0.37b15 [Aaron Giles]


- Protection devices unknown


- Driver emulates the Atari GX2 hardware


- Space Lords (1992): (Aaron Giles) This is the first Atari game to use a 68020 processor. Other games to follow on similar hardware include Moto Frenzy, T-Mek, and Primal Rage. The video and sound hardware is quite similar to the previous games (Guardians of the Hood and Road Riot 4WD). However, the SLOOP chip appears to have gone away, only to be replaced by something equally sinister. Space Lords uses this chip to produce the palette for the sprites, which is why all the screenshots have incorrect colors. The protection chip is also used to produce some in-game parameters, making it nigh impossible to play without accurate emulation.

- Moto Frenzy (1992): (Aaron Giles) Runs on identical hardware to Space Lords. Again, the protection device is not understood well enough to give accurate emulation. Graphics are drawn correctly, but the colors are incorrect and gameplay is fouled up.

- Road Riot's Revenge Rally (1993): (Aaron Giles) Sequel to Road Riot 4WD running on the same hardware as Space Lords / Moto Frenzy. Again, the protection device and custom ASIC prevent accurate emulation. Road drawing and sprite positioning are incorrect.


- 0.114: Couriersud added general save state support to the atarijsa and atarigen modules.

- 0.77: Aaron Giles added support for the MO command register (MO checksums now work), added missing SHA1 values, added another Road Riot's Revenge variant, some input port tweaks and removed 6502 speedups
