Most of those are addressed in the FAQ, aren't they? I'll list what I know.
Banjo-Tooie - See above Castlevania - See above Conker - See above Duke Nukem - Optimization Gauntlet - See above Getter Love - HCS is busy? I think the tags are incomplete. Killer Instinct - See above Lode Runner - I don't know (Is it in the FAQ?) Mario Golf - Based on the FAQ, it looks like the tags are incomplete. Mega Man 64 - There are some streamed tracks that aren't ripped. Most of them are probably not worth having, but I'm positive they exist. Ridge Racer - See above Rush 2 - See above Snowboard Kids - See above
So, while I don't have much to provide, I hope that helps a little. Mouser X over and out.
Only thing I can say about Getter Love (since I tagged and timed it) is that it is as complete as I am able to make it. The track timings may want checking over if someone really wants to make sure but I'm fairly confident all the tracks were looped twice where necessary.
Track names are a combination of translation where possible of a sound track that was released, mixed with guesswork and as a last resort whatever description sounds correct in the context of the game.
bump bmup! I'm thinking of doing a rerip of Robotech Crystal Dreams which will work... I have the code right in front of me but not the IDB (it got deleted), so yeah...
