Re: Diagnosing NES graphics corruption

It does appear ppu pin 33 has no continuity to the 373. The surrounding ppu pins connect in sequence to 373 inputs so i have a reasonable guess where it should go. Ill try to patch it tonight and report back. Just to understand your reasoning, you are saying ppu ad0-ad4 are working to address a 32 b...

Diagnosing NES graphics corruption

Howdy, anyone have ideas whats wrong with this toploader? Nothing obviously wrong with the board. Ive swapped vram on the board and the ppu and results are the same. Screenshot is title screen of action 53 vol 3. Other carts behave similarly. Haven't found any that show correctly. Program and sound ...

Re: TL-ROM Splatterhouse

Re: TL-ROM Splatterhouse

1.2a is the 1.2 patch + bugfix. I named it that to differentiate for myself. The mmc3 patch copies and rearranges a large chunk of the chr. If you're applying translation after, its not hitting anything above 128k chr. Translation should be first, then mmc3. This may end up being incompatible either...

Re: TL-ROM Splatterhouse

Where are you checking mirroring in fceux? The nametable viewer? If so i believe having it open will force fixed mirroring. Close everything and try again. Post a screenshot of what you hex edited if that doesn't work

Re: TL-ROM Splatterhouse

No, mmc3 does not use use the header flag that famirom reads.

The bug is mentioned on mottzilla's patch page. You should be able to google it with his name. Its literally a 1 byte replacement. You'll need a hex editor.

Re: TL-ROM Splatterhouse

so I'm 95% sure this is you having a bad rom. the currently available mmc3 patch doesn't set mirroring. i can duplicate what you posted by forcing mirroring to horizontal in fceu. everything works if it's set vertical. i haven't tested on cart yet but i bet yours defaults to horizontal. you have to ...

Re: What is this board?

By the label, the game seems fairly well known. Might be a prototype version of it? Or could just be the finished game sent out as a sample. Doesn't look like it was published outside of Japan so maybe they were shopping it around in North America. https://en.wikipedia.org/wiki/Challenger_(video_ga...

Re: TL-ROM Splatterhouse

Prg rom is 128, pin 30 can be left alone to be fixed high as long as he's doubling correctly which he has indicated he is.
