OS-native file load dialog On a few operating systems I can think of, your application can't even open a file unless the user has chosen it from the OS-native file load dialog. Otherwise you get a privilege violation. That's completely impractical and, dare I say, impossible. fopen("log.txt&qu...

Well, QuickNES isn't passing all of blargg's own tests yet. And I don't know if he ever updated his own copy of the emulator core to pass these tests, either.

I now have all of the undocumented opcodes required to pass blargg's CPU tests implemented in QuickNES, but polynes3.nes starts to fail after 26 frames: http://img684.imageshack.us/img684/2179/quicknes20110129080838.png It only gets worse from there. EDIT: Welp, I corrected the timings of several in...

For something similar to GSXSCC, you can look at "Emu de MIDI."

Also, FluidSynth is probably a more complete SoundFont synthesizer than Timidity.

Good idea. Maybe somebody can work that into the decoder I wrote ages ago, or maybe there's a better one floating around now?

A good converter need not do that much. An acceptable but expensive converter can brute force every possible filter and scale value combination for the least mean square error compared to the input sample data.

It's almost impossible to rewrite disks from a PC. The only methods I've found requires a parallel port and a stupid cycle-timed program that worked back in 1992 but donesn't work any longer (I tried - I even made a cable to connect my PC to the disk readed following all instructions but it just di...

Bregalad wrote:"offset per tile"
There was at least one fortress level in Yoshi's Island that used it for platforms waving in a sinusoidal pattern. At least I think it was using offset per tile, since they froze in place when I switched that off in Snes9x.

Toss the whole lot of files into the same directory and use relative paths? It shouldn't disable that.

Doesn't even open my sound output device under Linux, using the 64-bit beta Flash plug-in, version 10.0.45.2. The track skip controls do update the track title display, but the play and pause buttons don't seem to do anything.

Yes, but this also came with a tool to automate the compression. So far, minixsf and xsflib sets are all manually generated. Except for 2SF. At least I think that's how it's worked out.
