Man, I'm really spinning my wheels with this board. It looks like I have a Track & Field NZ (bootleg?)
My GQ-4X really doesn't like these Mitsubishi M5L2764 roms. If I read them enough times, I can eventually get roms 6 through 12 to verify with the correct Checksum. I'm concluding that those chips are good. The same CRC code is used for
- T&F
- T&F Centuri
- T&FNewZealand
I have been unable to verify any of Roms 1-5 no matter how many times I try them.
The labels on the chips all say "361" followed by the same identifiers I typically see on a T&F board: I01, I02,
003, I04, I05.
I have 2 blank 2764s I can use to program and troubleshoot. I've attempted to use them to swap out 1 or 2 of those first 5 roms that I can't verify. I've tried all of the 3 T&F versions, but no matter which version I burn and swap out it will not boot with anything other than the original chips.
other items of note, Shoestrings Test Rom 1.2 also will not boot.
I did verify that my 2764s work just fine by using them in place of roms 10-12
Just to remind, the game boots and plays fine with the original roms, but the colors of the sprites are jacked up. If anyone has any suggestions, I'd be grateful.
