I can test the demo on a PAL NES, but it's no longer available... could you upload another copy?

- Sure. It's not the original package, but I believe it's 3 files anyway. For PAL, you should try the CNROM version.

I've re-uploaded it. (I removed it cause people didn't seems to pay attention to it).
Note that only the PAL version is confirmed to work on hardware for now.

What's the difference between midscanline.nes and midscanline_b.nes? Both work fine in nemulator. The CNROM version doesn't, but I don't support PAL mode, so I guess that's to be expected.

- How exactly? Do you mean a black screen or garbage?

Huh ??

I think Zepper clicked the wrong post's reply button. Let me rephrase: For each ROM that fails, exactly what does it do that fails?

Nah. ^_^;; omg, here we go:

- You said the ROM doesn't work, but does it display something or black screen only?

Well I said it does work on PAL and is untested on NTSC (but very very likely to work as it only differs in timing, which is adapted, from the PAL version).

- Ah, ok. ^_^;;

Zepper -- saw that you released a new version of RockNES. Did you fix this issue? If so, what was the problem?

Zepper · Post by **Zepper** » Tue Feb 02, 2010 8:37 am

- I didn't fix it. It's probably my gfx engine.

Sorry for bumping it, but such problems are still pending. Any help? This glitch occurs in Mega Man 3 (glitched scanline on Magnet Man, instead of Shadow Man), Rad Racer 2 and Gauntlet 2 (glitches at right).

Are you sure the two are related? MM3 is a single line issue where RR2 is multiline.

For what it's worth I don't see how the MMC3 could cause the RR2 issues, my guess is your comment about it being your gfx engine is correct. I can see how the MMC3 could cause the difference in MM3 but if it was you wouldn't be able to pass blargg's tests like you now do. I guess it's possible you've got MMC3 mirroring issues but not IRQ. You probably knew that though...

Screenshots:

- Mega Man 3: glitch should be on Shadow Man box, and not on Magnet Man.
- Rad Racer 2: right side is glitched.
- Gauntlet 2: glitched at right side, 3 segments of +-20 pixels.

All these games use IRQ. If I adjust the IRQ to trigger later (much like mapper 64), the glitches are gone... but I disagree.
