DC drive is a modified Yamaha 400R (as long as I remember it has a different chip so it can read gdroms), I don't know its read offset
Please don't take dumpcast db for redump db, gaps from dumpcast are all wrong and bad. Here is Redump and not dumpcast.
We don't need to dump gaps on the fly or any offset for HD area*, if the author of dcsdrip (or someone else, I don't see any source code on his website http://f17.aaa.livedoor.jp/~takotako/dc … p#dcsdrip) can modify this prog to read data from sector to sector in raw audio (one single audio mode file for all HD area data - sector 44990-549150 -**, the same we do on PC with cdrwin), we can use it to get right tracks from HD area using ICE.
*When cdrwin dumps HD area in audio mode it has only the drive read offset correction, then is ICE that scramble and splits the tracks. SD area can be dumped on any pc drive.
** it's sector 45000-549150, but because some discs have negative offset it's better to dump 10 more sectors before HD area default start.
