help with NES parodius Repro

Post by chunk337 »

Ive made a bunch of MMC3 repros so i am familiar with the wiring. however, i made a european copy of parodius and the game plays but there are tons of graphical glitches. most of the text and music are fine. I have checked every point for continuity and shorts and found no issues. Is it possible that its just a badly burned EPROM or is there something else to look for? I believe this game should play on an NTSC console because i have played it via everdrive.

That looks like you somehow got the pin rewiring wrong. The tiles are are credible tiles, just the wrong ones for that moment. And a bunch of banks are correct even so, such as the text.
