Bugs:
  • [debug] Black Screen. Tafoid (ID 04031)
WIP:
  • 0.139: Atari Ace converted the Atari MediaGX driver to use driver_data. Also fixed Area 51: Site 4 hang after loading via internal UI (multisession).
  • 0.137u4: Guru added newer Area51: Site 4 BIOS (a51s4_bios_09-15-98.u1).
  • 23rd January 2010: Smitdogg - Ninjakid dumped Area 51: Site 4 (Sept. 11, 1998) and sent the motherboard to Guru to dump the BIOS and for possible decaps.
  • 0.136u1: Miodrag Milanovic updated PIT8253 counter even if there was no elapsed cycles (this only affects fast drivers like at586 in MESS). This fixed the Area 51: Site 4 regression (black screen instead of intro).
  • 0.129: Aaron Giles fixed interger overflow with -debug in 'Area 51: Site 4'.
  • 0.115u2: Fixed input and coins.
  • 0.111u4: Ville Linde improved sound output in the MediaGX driver. Changed DAC sound to DMA-driven DAC.
  • 0.110u4: Ville Linde added workaround for broken MediaGX driver.
  • 0.101u2: Ville Linde added Area 51: Site 4 (Atari 1998).
  • 8th October 2005: Ville Linde - I've been working on a Atari MediaGX driver for a while now as a side effect of the recent x86 and PC emulation stuff. Area 51: Site 4 now runs its attract mode just fine. The game isn't playable yet as the controls haven't been hooked up yet.
  • 24th December 2002: Guru - Area 51 Site 4 (Atari 1998, uses 2.5GB hard drive) arrived. Thanks to Mr F.
