I don't have that much knowledge but i'm trying to.
As far, very simple work done involving eeproms and gals (also added 74ls74 at H10). Unfortunatly i don't have any Charlie Ninja/Osman/Gonta to check deeper but i hope in your help.
Right know the game is kind working underneath, but the graphic is all messed up.
There is a Jumper section right above the 156 to figure out with the "real" board, i wasn't able to find any information about the 156 custom/cpu (are there any schematics of these boards?)
I've note down where the connections go throught, they originally match like 1+1,2+2,3+3,4+4 and i tryed to swap them around with no real luck, can someone confirm these locations are correct?
I've heard that the conversion is kind possible but figure out the hardware modifications is not easy
