I did this and unfortunately still blank.Swap the GP 15 top board with one from a tekken 3 to narrow it down.
Not sure how to check the roms. I did recap the entire board and switched the fighting layer top board with the tekken 3 top board. I was able to play tekken 3, but the fighting layer board is still blank. It keeps flickering, unable to sync. No sound, no boot, just black.>I did this and unfortunately still blank.
Next job is checking the program roms / dumping them to check if the flash is corrupted.
If you swapped with a tekken the top board is not a problem.
This will be a very easy job for him compared to some of those nasty CPS3's and crazy mods he's been doing lately!Pinging @cruzlink2
Sounds like the top board is good anyway. The problem will be the program flash i think....I already did a re flowing of the psx gpu and cpu on the daughterboard and no dice, I am gonna borrow the tekken tag 1 board at https://x.com/ArcadeBrooklyn .
Thad way I can swap cpu or rom boards to see what the deal is.
