0.136u3 [Roberto Fresca, Tomasz Slanina, Gerald Vanderick]
WIP:
- 0.171: Changed description to 'Joker's Wild (B52 system, BP55114-V1104, Ver.054NMV)' and clones (B52 system, set 2) to 'Joker's Wild (B52 system, WP02001-054, Ver.031WM)' and (B52 system, Harrah's GFX) to 'Joker's Wild (B52 system, BP55114-V1104, Ver.054NMV, Harrah's GFX)'.
- 0.161: AnonyMous dumped GFX roms for clone Joker's Wild (B52 system, set 2). Changed visible area to 544x436.
- 0.154: Sigma B52 updates: Improved inputs. Added preliminary sound. Fixed DIPLOCATION. Added NVRAM. Various cleanups. Added coin lockout. Added lamps layout [Sandro Ronco]. Added M6809 (2MHz) CPU2 and YM3812 (3579545 Hz) sound. Added gambling control with 4 buttons and 1 coin slot. Fixed dipswitches.
- 0.153: Converted Sigma B52 driver to use the new HD63484 [Sandro Ronco]. Fixed gfx1 rom loading.
- 0.148u2: Nathan Woods fixed interrupt handling in Sigma B52 driver using 6809 that pulsed interrupts in a way that broke with the new 6809 core.
- 0.136u3: Roberto Fresca, Tomasz Slanina and Gerald Vanderick added 'Joker's Wild (B52 system, set 1)' (Sigma 199?) and clones (B52 system, set 2) and (B52 system, Harrah's GFX). New driver for Sigma B52 system. ACRTC implementation is a bit hacky due to its preliminary emulation status [Roberto Fresca].
- 7th February 2010: Roberto Fresca - I started to write a driver for Sigma B52 system. This platform is a complex gaming system based on 2x M6809 CPU's, 1x YM3812 sound device, and a very complex video controller (H63484 ACRTC). Thanks to Tomasz Slanina that kindly joined efforts hooking the ACRTC stuff, and Fabio Priuli converting this controller to a device. The ACRTC implementation is a bit hacky due to its preliminary emulation state. Here are some snaps from Joker's Wild (B52).
- 4th February 2010: Roberto Fresca - Initial release. Pre-defined Xtals. Started a preliminary memory map. Hooked both CPUs. Preliminary ACRTC support. Added technical notes.
