0.63 [Aaron Giles, Nicola Salmoria]


TODO:

- Measured against a real PCB, the games run slightly too fast in spite of accurately measured VBLANK timings.


WIP:

- 10th July 2003: Aaron Giles fixed the timer bugs that caused the Art & Magic and exidy440 games to fail, and the Seibu sound system is also fixed now.

- 20th January 2003: Aaron Giles fixed the protection in Cheese Chase.

- 19th January 2003: Aaron Giles fixed the frame rate in the Art & Magic driver.

- 18th January 2003: Aaron Giles did some general cleanup on the Art & Magic driver and corrected the CPU and sound clock frequencies.

- 17th January 2003: Nicola Salmoria and Aaron Giles fixed the remaining graphics glitches in the Art & Magic driver. Aaron Giles also abstracted the TLC34076 palette chip emulation used by Art & Magic, Battletoads and a few other drivers.

- 15th January 2003: Aaron Giles finally figured out the protection in Ultimate Tennis, making it fully playable.

- 13th January 2003: Aaron Giles fixed the sound banking in the Art & Magic games and improved the protection emulation, but it's still not complete.

- 12th January 2003: Nicola Salmoria further improved the decryption of the blitter data in the Art & Magic driver and hooked up zoom in it. Aaron Giles fixed the dipswitches in it and figured out the protection interface in Ultimate Tennis and Stone Ball, but the protection data is missing so they still aren't playable.

- 11th January 2003: Nicola Salmoria improved the decryption of the blitter data in the Art & Magic driver.

- 7th January 2003: Aaron Giles sent in a work in progress driver for the Art & Magic games that supports Ultimate Tennis, Cheese Chase and Stone Ball, the problem being that the blitter data format is encrypted so all graphics are garbled.

- 6th January 2003: Aaron Giles fixed some things in the TMS34010 CPU core that will be needed for the Art & Magic games.
