- 0.118u2: Removed 16x 'Unknown' dipswitches.
- 13th August 2007: Roberto Fresca - Added "El Grande - 5 Card Draw" (new). Constructed a new memory map for this game. Reworked a whole set of inputs for this game. Patched some bad bits in GFX rom d1.u68 till a good dump appear. Updated technical notes.
- 0.117u2: Roberto Fresca cleaned up the inputs in Gaming Draw Poker and changed the hold buttons to "discard" since they are in fact discard buttons.
- 23rd July 2007: Roberto Fresca - Cleaned up the inputs. Changed the hold buttons to "discard" since they are in fact discard buttons. Updated technical notes.
- 0.114u4: Rewrote the vp906iii driver [Roberto Fresca] - Game now playable: Decoded GFX properly. Rewrote the memory map based on program ROMs analysis. Hooked two SY6520/6280 (M6821) PIAs for I/O. Hooked the SY6545 (6845) CRT controller. Fixed size for screen total and visible area based on SY6545 CRTC registers. Added partial inputs through PIAs. Added proper sound through AY8910 (mapped at $0840-$0841). Proper colors through color PROM decode. Added some game-protection workaround. Added NVRAM support. Changed visible area to 256x248. Fixed gfx2 rom loading. Added 'Maximum Bet' and 8x 'Unknown' dipswitches. Changed description to 'Gaming Draw Poker'. Renamed (vp906iii) to (gdrawpkr).
- 27th April 2007: Roberto Fresca - Rearranged GFX in two different banks. Decoded GFX properly. Rewrote the memory map based on program ROMs analysis. Hooked two SY6520/6280 (M6821) PIAs for I/O. Hooked the SY6545 (6845) CRT controller. Fixed size for screen total and visible area based on SY6545 CRTC registers. Added partial inputs through PIAs. Added proper sound through AY8910 (mapped at $0840-$0841). Fixed AY8910 volume to avoid clips. Proper colors through color PROM decode. Demuxed inputs (thanks to Dox that pointed me in the right direction!). Added some game-protection workaround. Added NVRAM support. Renamed driver, set and description to match the real game. Added technical notes.
- 25th April 2007: Roberto Fresca - Mystery partially solved. I found a picture of the "CEI Video Poker" (system 904) that clearly show an error. The background is definitely blue. Note that you can see the words "Cal Omega 1981" burned at the bottom of the screen.
- 24th April 2007: Roberto Fresca - After a vp906iii rewrite Gaming Draw Poker from Casino Electronics Inc works. The hardware seems to be an evolution of Jack Potten's poker. Former than 906iii system (CEI). They replaced the discrete sound system with a AY8910 to improve sounds. Different memory map, multiplexed inputs, ets. Cards GFX have the following unused logo (Omega Electronics?). The game is working properly with sound. Lamps are a big mess and I'm still trying to fix them. Palette pass through a transformation, so the background could be blue or black, either. Need to check it against the real thing (if one day appear!!). A big thanks to Tomasz Slanina that pointed me in the right direction to demux the inputs.
- 0.99u2: Curt Coder added '906III Video Poker' (Casino Electronics Inc. 1985).
