Okay, judging from the link you might know what I'm about to ask, but in short, the idea is to add a file format found in the companion MegaCD/SegaCD CD-ROM for the recent Genesis/MegaDrive JRPG game, Pier Solar and the Great Architects. Of course, I mean the alternate ISO, found here. ;)
This game does what no other Genesis/SegaCD game has ever attempted, let alone conceived: Not only does this game employ the Tiido sound system (PCM software-mixed 2 channels at 22khz, addition to the usual FM/PSG), but when the companion CD is inserted, it streams ACTUAL LOOPING PCM! (8-bits @ 32KHz Stereo) As in what would be standard when redbook would be rendered OBSOLETE! (yeah right! :P)
Anyways, I'm doing this in the hopes of one bitchin' crossover project. Besides, Tulio Adriano, one of the soundtrack's composers is awaiting word from DarkPulse for a site update, now that the VGM version's finished. ;D
