[Dreamcast] Question about offsets.

Example: Comic Party (Disc 1) https://redump.info/disc/39505/ Write offset -174.

In the ring under the field, Write offsets, you have put Image-174|NULL

Can the NULL part be got from any where, example in the ice log.

Code: Select all

ice @20090609 / themabus@inbox.lv

dense.bin

Yes, for ice log:
tossEAC wrote:Combined offset (samples) : -168
that value - (drive read offset from drive which was used for dumping with ice)

Which is then the High Density Area (HDA) offset.

So should I make a new post with various ice.log files, that way you can work out the missing offset.

The drive I used/use has a +6 offset, so -6-168=-174 so the HDA has the same offset as the LDA.

yeah, for this particular case both write offsets are equal -174

a new post with ice.log files would be nice, please mention your drive read offset there and put all logs into an archive as attachment.

Will do, only I don't have all the ice logs for all my dumps but I will collect up what I have and post them, leave it with me for a day or two.
