Ok, twofold question here:
First: What is the technical legality on redistributing chip tunes? I've got a few off the internet from respectable looking sites (Mind you, for games I own). I've got .ogg re-encodings of them that I could put up if it would be permissible.
Second: Is there any way to add in plug-in support for Audiosurf, like BonkEnc supports Winamp plugins? Like allowing .dll's containing the correct handling information being added to a plug-in directory?** If you do not own these games, do not download these songs. **
I'm gonna go with a forgiveness rather than permission thing, since it won't really hurt the makers (since they would be near inable to sell the songs in this form), and since the only people interested will be those who have the games, since it's more of a nostalgia thing.
I'm starting with Sonic III and Knuckles.
It's in 7-zip or .exe format. Live with it. The .exe has the .ogg's in a sub-folder, the .7z has them with no folder containing them.
