There's a download on knightTeen87's site for the entire King's Field soundtrack + Eternal Ring, he even has all the midis.
Hey MT, long time no see. :)
He doesn't have King's Field Additional soundtrack. Sure, the soundtrack CD from the Dark Side Box has some music from the KFA1-2 (including one remix from the game), but I always wanted to have all tracks and remixes of original KF music from KFA in my collection, and unfortunately he and OrangeC gave up on their attempts to get the music from the game. Plus, his site doesn't have KF Arrange album (~Invitation to the Graveyard~).
I've ripped about 12 tracks so far, but this ripping procedure is kinda tricky, so I need to beat the game the game to get everything. If I manage to get everything, I'll gladly share the music, if I don't -- might as well drop the guide how to do it and release what I have.
Glad to talk to you under different circumstances. :P
