I checked the background chips on the lowest board nothing suspicious.
I reinstalled the original game ninja spirit and so far no glitch at all. So I guess, I should first reseat all the EPROMs from the multi
I noticed some differences for the staples from the manual are strange not like in a real sfc game. Also there are some cuts inside the box that doesn’t existe in a real one
I bought one of these. I knew it was a fake one. I would not buy a real one complet anyway. It is well done. The pcb is an official Nintendo but from 1992 and not 1990 like in the official one. They took the pcb from another but real game so basically it s a conversion. I have also the real one...
If the background graphics are located on the bottom board I don’t have access to the chips. I need to make a long power cable.

Sure, the game was working perfectly before installing the multi, even just after, I could play and the next week I observed these glitches. The pcbs are clean I checked again today, I could not seen anything wrong on the pcbs.
