Re: Need help with compressed tiles

A graphics edit is not enough: as you see, 2-4 use the same graphics, just palette swapped. So it needs some code edits too. Perhaps it'd be better to ask at romhacking.net than here.

Re: Design guidance for 3D Engine on SuperFX

Probably the old NES trick? Higher priority sprite goes behind bg, blocking the lower-priority sprite's pixels, even though the lower-prio sprite is above bg.

Re: Mmc1a versus 1b2 etc

If the other banks already have data in the vector position, such modifications would be very hard.

Re: Minecraft Clone on the NES

And how many writes can unrom-512 and gtrom flash tolerate? The worst modern flash is only 100 writes, you'd kill it in half an hour of minecrafting.

I am so pissed at the modern fad of only posting videos. No I'm not spending X minutes listening to you when I could read the meat in 10 seconds.

No, verilog is turned into hw, it can't be dumped via software. "Dumping" hw is decapping and manual transcription.

Re: Using Leaked Nintendo Source Code Poses Serious Legal Risk to Emulators [link]

He's talking about a Wii POV; for N64 emulation, the verilog being there should be more useful. In the last tweet he says Now if the leak *really* contained full Verilog for the GPU, for example, that could help resolve long tail emulation mysteries... But no sane emulator developer is going to want...

Do we need to transclude [[VRC IRQs]] into the VRC4 page?
Actually having it in an iframe or similar would be rather good. No other mapper page has such a split, it breaks user expectations.

Re: Nintendo legacy console leak

Screenshots of it show Nintendo used CVS as far back as the N64. That's a pleasant surprise, source code management in an industry known for losing its sources.

Re: Optimizing scroll changes after MMC3 IRQs

The various modes affect when the MMC3 irqs trigger. 8x16 sprites, using the "wrong way" halves for bg and sprites, etc etc. Maybe you can find a config that works for both the game-side and earlier irqs.
