90 min. CD-R's?

[Slider One]

Hi folks!

Couldn't find an answer for this in other posts. The thing is, I want to make all of my games self-bootable and of course there are some, which make problems just because of size.
It was possible to get Sonic 1 on a usual 80 min. CD-R by deleting the jap. voices and Ecco with the patch. But there are still some more, that won't fit, unless I downsample something.

So I thought, it'd be a much easier deal to bring them onto 90 min blanks. But I'm not sure if that's the better idea. A while ago I burned Head Hunter CD1 onto such a disk, cause I didn't have one of my usual Sony CD-R's left. I noticed, that the laser made a lot of noise during loading and I was wonderingg if that's normal with that game or if the laser had problems reading the disk.
(BTW it was an Intenso 90 min. CD-R)

So, has anyone experienced something similar, or even tried this?

Another thing. In the above case, no game data was written behind the 79:57 min mark. But that would happen, when I used the echelon method to bring such a full-size game on CD. As far as I know, Bin2Boot writes the second session at the end of the disk. In this case just the boot-sector would be behind this mark. However does the DC even have any problems reading behind it?

It'd just be ***** if I discovered at the end of a game that my DC suddenly crashes...

Any ideas, experiences?

BTW, sorry for my bad english at the moment (has been a looong day)

my copy makes a load of noise while loading too....but its only a 80 min cdr

Thanks for your answer

That clears things up a bit for me. After two coasters that made me believe that Discjuggler doesn't support overburning Bin2Boot converted Images, I managed to get Rainbow Cotton selfbooting the Echelon-way with CD-Record. I added the option "-ignsize" when burning the second session, but I don't know if it's necessary.
Nevertheless, I noticed that the speech in the intro and other sequenzes seems to be out of sync. Quite irretating.
Think I'll burn it at least once non-booting on a usual CD-R to see if it shows the same there...

My experience with 90 min CDRs on the DC is as follow:

I burned an VCD which covered a whole 90 min CD (yes, i know VCD's don't have error correction and you gather additional ~100MB) and the CD is FULL to the MAX. I threw it into the Dreamcast VCD Player and it played through the whole movie without errors or anything. For me it's proof that the DC can read 90 min CDR's, because if it wouldn't, i wouldn't been able to watch the movie to the end, right ? K. I think the DC isn't able to read 99 min. CDR's because anything that goes beyond 90 minutes has negative LBA Values. And i don't think the DC will read LBA's with values like -98 or whatever.

Another one:

I ripped AITD4 from the GD and made it selfboot using the 45000 LBA method. (2 Audio Tracks, binhacked ip.bin). I had to downsample/remove almost the whole movies and the .XA files, but it worked on a 80 min. CDR. Later i tried the same with a 90 min. CDR, with less downsampling/removing files, but cdrecord didn't let me burn beyond the 700mb mark. Ok, i created an CDI Image with DiscJuggler (45000 Audio in 1st session, game data in the 2nd) and manually copied/pasted the 32768 bytes of the bootstrap data (from the first working copy, see above) into the CDI (to the same offset like in the first working copy) which i wanted to get onto the 90min cdr. OK, burning went fine but my DC wasn't even able to find a bootsector (no SEGA Logo appears after the swirl). I dunno if this is related to the 90min cdr, i have absoluteley no clue....

P.S. Does anyone know how EXACTLY the BIN2BOOT method works ? I mean game data before audio data etc...

[AreuWho]

err, i mean : game data before *BOOT* data

my problem is Strange!

i can burn the Un-selfboot image to 90/99 CDR with my burner

but i Can NOT Burn selfboot image, always got an error

that is my burner can not burn image more than 1 session

who can tell me why?

99 minute CDRs do work on the DC. Just make sure your burner is compatible with them before you bother to make one.

As for your Head Hunter making a lot of noise, maybe you should resort the files on the disc to cut down the loading time. Mine doesn't make that much noise.
