I just have the games organized in such a way that I couldn't help but see that there was a GB and GBC game by the same name. I just didn't bother to check, as I was kind of on a spree. It was simple enough to rip, so just keep the smaller one.
Incidently, Mogura de Pon! pack on your site looks to be put prematurely, has GB not GBS and the header data for the GBS inside isn't finished (160 subsongs, while only 8 play, bad header tag data, etc).
I accidentally packed the .GB conversion instead of the GBS, and you got a look at my default header values. I hadn't reconverted the GBS to .GB after filling in the details, so it looked incomplete.
I use gamefaqs to check for game names, so it's always possible to get bad data.
Looks like gamefaqs was wrong this time. Oh well. Ace Striker up now too.
The stuff currently available is great, and I do believe Allister Brimble to be their studio composer, and the guy's a classic VGM composer (very solid output on Amiga/GB Advance).
Same deal here, Amiga veteran Matt "4-mat" Simmonds is the studio composer for this developer. And both currently available rips (Air Force Delta and Warriors of Might & Magic) are all kinds of awesome.
Don't think there's much to be said about those 4 companies above. Solid music output overall, though how much of it is developed internally, and how much is just published is hard to tell. Still, there's bound to be some great tunes there. :)
