comg080: MAME ROM Information.


History:

Arcade Black Jack (c) 1981 Cal Omega.


- SOURCES -


Game's ROM.



MAME Info:

0.125u7 [Roberto Fresca]


WIP:

- 0.139u2: Roberto Fresca fixed 'Cal Omega - Game 8.0 (Arcade Black Jack)' - Game now playable. Injected missing start and NMI vectors to comg080, from an exhaustive program ROM analysis / reverse engineering. The game now starts ok and is triggering proper NMI's. Added inputs from the scratch for comg080 and promoted game to working state.

- 24th August 2010: Roberto Fresca - Finally, after an exhaustive analysis of the code, got the *first* Cal Omega Black Jack game running. The last ROM is in fact a bad dump, since only the first half of the data is present. This means that start and NMI vectors (among some byte-checks) are not present in the current dump. Since is uncommon that another board will ever appear, just reverse-engineered the program to get the proper vectors and checked values. The last subroutine (end of first half) remains clipped, but I didn't see a call for it. Maybe was a leftover. And YES... These vectors/values are ACCURATE. There's no way to run the game without these exact values. The bad dump wasn't touched. The data is injected on the fly through driver init.

- 0.125u7: Roberto Fresca added Cal Omega - Game 8.0 (Arcade Black Jack) (Cal Omega Inc. 1981).
