CPS-1.5: Punisher Conversion

Update: The new GAL chips came in. I compared the GAL files I have with the ones from MAME and they did match. I programmed the new chips, but I get the same black screen result. I am totally stumped at this point. The kabuki should be good because Tenchi wo Kurau II works just fine. I think I programmed the qsound chips correctly, they verify against the MAME files successfully. The same with the program roms, they also verify successfully.

Does anyone know of a reputable source who I can send my boards / chips to, who can successfully convert Punisher and Cadillacs & Dinosaurs for me?

Thanks!
 
Something you might try if its easy for you to reprogram the program roms. In your 23 program rom, do a hex search for this

Code: 
39 30 F1 00 FE 9F 00 0C 77 00 F4 66

and replace it with this

71 4E 71 4E 71 4E 71 4E 71 4E 71 4E

In theory there should be one occurrence of it near the beginning of the rom. Its the code I was talking about before where the main cpu goes into a endless loop waiting for the kabuki cpu to write a specific values to a shared memory address. The replacement bytes nop over the check. If the game boots there wont be any sound, but it points to the issue being with the kabuki/qsound stuff.

Thank you. I’ll give it try 👍
 
I tried changing the line of code and reprogramming the chip, but still a black screen. I appreciate it though.
 
ok, one last thing to try that I can think of. You said that openkey/infinikey worked fine for you with Tenchi wo Kurau II right? On the D board, try using that original d9k pal with your conversion.

@Sbarb18 did reach out to me. I suggested that he try leaving out the OpenKey devices for the C Board and Kabuki and instead use the files and mod procedures on the Dead Battery Society website instead. I was able to convert two Muscle Bomber boards to Punisher and C&D using the instructions on that site.
