Both of them are line-in recordings, but they’re probably the best rips that are out there currently. Is it even possible to do digital extractions on the music files from VB games? Back in 2007 I was told that was impossible – I’d love to be proven wrong on that, though! (Yes, I’m Blue_Kirby2… I’ve switched to a different name since I don’t like it anymore. :P)
Good rips, yes, but they end with a fadeout. And I’ve noticed that The Final Stage repeats a couple of times (maybe also other ones, I haven’t checked them all yet). Anyway, they’re stereo, which I personally find annoying sometimes, but some may like that.
You can now listen to/record a large number of SFX-free game soundtracks from VBJin with the MusicSelect.lua script. Music ripping notes have been made for games that aren’t directly compatible with the Page Up/Page Down music select method. Completing the entire game list is an ongoing project.
