Hey
Have been wondering about the PROGBK1 / CHA512 pcb set for a while..
Would there be any way to adress big P roms on this PROGBK1 board?
Later games such as metal slug 5 and Samurai spirits 5 special have bigger P roms than this pcb originally supports..
(BUT I found out that at least ms5 has garbage at the end of the 8MB P rom file that can be deleted making it fit)
However my focus is now Samurai Spirits 5 Final Edition! Which also has 2x 4MB P roms
Since we have so many talentet ppl on these boards I though I would ask for help making this possible
Its the P1 slot that max can adress a 27C160 eprom (2MB rom file) that needs to be modded to use 27C322 eprom (4MB), or is its the P2 slot that needs to adress 6MB?
Physically it fits but I dont know how the banking works :/
Of cource there needs to be adapter pcb fitted with flash and leveltranslators for all C and V roms, but they already exist, so its only the P rom banking thats holdig this back
