Re: Mesen - NES Emulator

I see Game_Music_Emu's Nes_Apu and Nes_Oscs already do this, or close enough. They reset phase on writes to $4003/$4007, and they maintain pitch correct phase during periods of silence or inaudibility. I just don't know what else could be "wrong".

Well, I didn't think of that. Removed, but he probably already got it.

I uploaded both the patches I have here:

[removed]


Unfortunately, the MMC3 conversion was made against the version of the translation that used that silly Gryzor title instead of Contra. This prompted me to add VRC2 support to QuickNES.

I found that QuickNES was a good 50% faster when built with MSVC 64-bit, compared to 32-bit. Of course that was in 2009, so it was obviously built with MSVC 2008. For example, running Battletoads (U) into a null output with no throttling, for 4 seconds: 32-bit: Performance: 8684 frames per second, w...

Some cartridges could batteryback the RAM while others may not. An example of this is on MMC5. Carts exist with 16K of WRAM that's half battery backed and half that isn't, while other carts contain 8K or 32K of WRAM which is battery backed. A size field won't tell this apart very easily unless you ...

Emulator. Already supports this format. Insignificant because it can't play all of the games preserved by the set. Oh well.

And now QuickNES is the first NES emulator to support the ZapFC database. Currently, it supports the database raw or packed into any of the supported archive formats. (zip, gzip, rar, or 7-zip LZMA/LZMA2/PPMd) It searches the configuration folder first, then the program folder, for a file named ZapF...

Okay, I'm not sure I'm doing this correctly.

But if it includes .rar, that might be why it's not in Linux or FreeBSD: the unrar code is under a non-free license. That's strange, I wasn't asked to pay anything for my copy of it. It's not whether you paid anything for it, it's whether you're Free to do whatever you want with the source code, in...

It is bundled with older versions of bsnes, in the snesreader library source. It does bundle the unrar library source, but that can be disabled and excluded. I don't see what the big deal is about that anyway, other than the whole idea of "you may not use this decompression code to reverse engineer ...

Imagine finding a bunch of ARC or LHA files today. Funny thing, isn't LHA still used as widely in Japan as ZIP is used everywhere else? blargg's File_Extractor library seems like an acceptable solution for reading these archives, except that no Linux or BSD distributions seem to want to supply it. ...

Okay, I stand corrected. If you don't consider rewriting your programs into weak-sauce toys to be impractical, then you're right.
