Any news about CD-i Ready format support? People ask me about it sometimes, the last person was iR0b0t

DIC needs to read the audiotrack + pregap with data starting from LBA 0, then to descramble data sectors (I think the data track in the pregap has its own track number somehow, so it's not really correct to leave all the data sectors as scrambled).

I tried DIC, it did dump it okay, but it descrambles data sectors. They should be left scrambled. Track mode is AUDIO.

Ah, so it works now. Last month another dumper has shown me some DIC error logs for the Alien Gate (also CD-i Ready).

Track mode is audio, but doesn't the data part in pregap have its own track number in this case?

No, its numbered as track 01.

Isobuster misinterprets leading track number as 0 or 2

DIC can't read "no track 1" disc yet. Is this CD-i Ready?

CD-i Ready Test dump (attached)

I firmly believe the data part should not be unscrambled.

Skipped being unscrambled.

And I noticed the format type of CD-i ready wasn't "CD-i"
I understood DIC can't dump CD-i multi track disc, not CD-i ready.

It dumps fine now, thanks.

Any chance to add the first 16+512? bytes from LBA 0 sector (45000 for "gd" mode) into maininfo.txt? So we wouldn't need to ask the dumpers to provide these for Saturn, Mega CD, Dreamcast dumps.

And have you thought to add the support for the swappable non-Plextor drives? DIC could read scrambled sectors with 0xBE command in this mode and people could use more common drives to dump properly.

Added LBA 0 of the sega disc into maininfo.txt

What is this?

Yes, I confirmed ASUS BC-12D2HT could read it.
