This creates an impossible situation where tracks overlap.Р вЂќР’В«ut wait, what if we treated this new image just like the old dumps and actually did apply the fix for audio tracks as usual? Then it'd be 355602 plus 150 fix which equals 355752 and it checks out. See the problem? Track 4 starts at 355602, which is less than 355752. Let's add this length to it's starting address, to see where it ends: 45000+310752=355752. Since it's missing the pregap I mentioned, the actual length of the track is 150+310602=310752. Track 3 file is 730535904 bytes long, that is 310602 raw sectors. gdi file says this for tracks 3 and 4:Р вЂќР в‚¬ 45'ChuChu Rocket!

(Europe) (En,Ja,Fr,De,Es) (Track 04).bin' 0 My guess is the new dumps were supposed to overcome that, but instead are plain broken.Р вЂќР вЂћs an example let's take a look at Chu-Chu Rocket, the PAL version.

For GDIs it means you need to adjust for missing pregaps (not really needed) on data tracks and starting address on audio tracks.

But small flaws can be corrected if the method is good in principle and the changes are always consistent.

GD-ROM images made using GD drive in Dreamcast are not perfect either, but frankly no CD image format is, or will ever be, unless we store raw EFM stream (assuming we can even read it glitch-free, which is debatable). gdi files and typical user has no way of knowing if it's a proper dump or not. The worst part is they've just shoved all their changes into. Well, the group(s) in question decided they know better and introduced changes into tracks' positions and lengths - to 'fix' things I guess. I did that too once, other than having slightly different 'audio offsets' there is nothing preventing such dumps from working - if done correctly.

Seems like there is a group, or groups, that started doing GD-ROM dumps using PC drives with a so-called 'swap method'. In other news, my testers notified me of some recently done Dreamcast dumps that appear to be broken on GDEMU, so I investigated. More details will follow once I get everything sorted out. After that, when I can tell just how many people are actually going to pay for it, I will decide if I will continue or not. Decision has been made, there will be a short production run of GDEMU soon - as in, a few weeks.
