This is a very low-level block-allocation optimized disk. It has to be that way in order to fit all of the content (700 MB plus CDDA). The disk works flawlessly on an undamaged GDROM. As a developer, I know a ton of people will have problems, but I can't code for out-of-spec drives.


GDROMs are widely worn. I have five Dreamcasts, and this boots correctly on three of them, while the other two run almost everything. What is the problem? .. When a GDROM wears out, it gets out of calibration. You have both a high and a low LBA. Wear indicates that it has put the most effort into whatever it has gone to. When you adjust a gdrom, you use a set of CD-ROM disks, one with a high LBA and one with a low LBA, and you try to get it in the middle of those two. As a result, everything is loaded. 100% This is a very low-level block-allocation optimized disk; it has to be that way in order to fit all of the content (700 MB plus CDDA). The disk works flawlessly on an undamaged GDROM. In my first video, I demonstrate how I have three Dreamcasts with low hours that boot and work flawlessly every time. I have two others that will not boot at all, but those two will work with most burned games and gdroms. Sadly, this is a common problem. As a developer, I know a ton of people will have problems, but I can't code for out-of-spec GDROM drives.

collection is awesome!!! but for some reason, image on SNES games (T.I.T. NTSC and PAL) is shifted down, cutting almost 20-40% of bottom image :(

Played a DARK CDI version with Shredders Re-Revenge rom on burned CD-R with AV composite video output

Interesting i have japan dc works fine but i only use vga output.. I have seen it work correct on ntsc with av cable but it's never going to be correct for genesis that needs 480p.. Kos must be getting confused on -J somehow..

It's so funny to have ported the collection to the dreamcast :). I don't know if it will be my way to go playing those games, but it's worth giving a try :). Awesome job!
