The new Plextor writers (IIRC) can read 1 GB CD-R's.

They have certain Plextor technology that can over burn cd-r's to 1gig, but the cd's cant be read in another companies drive.

The 1Gig CDs are not the same as Dreamcast GD-ROMs.

wonder_k · September 8th, 2003

sure they're not but the principle of recording high-dens tracks on a gd is the same, right?

S.SubZero · September 8th, 2003

GD-ROM discs have an inner layer which PC's can read, then they have a thick area with no data, and then starts the GD part of the disc with the 1GB of data. It's not one consecutive data track. Any drive trying to read a GD disc would need to understand these parts.

Regulus · September 8th, 2003

So if u had one of those plextor drives and used a combined program and re-flashed firmware, technically, it would be possible to read a GD-ROM.......idk.....maybe not.

scottlc · September 8th, 2003

No, it certainly would not. As someone already has stated the data is pushed to the edge of the disc.

don't say it's impossible! it's not like splitting an atom using your grandma's butt you know?

but seriously, the amount of time and hardware (which is bound to break several times) isn't worth it.

every elemtary school kid might know that but if it gets more and more experience with things it also is bound to recognize the fact that if it knows how the data is written to a gd there's only a working implementation missing, right?

example:

compare zip & rar. surely no pure-zip archiver is able to read a rar-file and the other way around but there's a specification which makes it possible to recreate the process.

anyhow, the idea of building a pci-controller for a real gd-unit sounds much more pleasent...

I don't why you guys are saying no way and making jokes, He said it will work with cdr backups. My question is is it going to use self boot cd's or non self boot cd's? Also i'm afraid that pc's won't be fast enough.

Regulus · September 9th, 2003

im guessing the Emu will boot the CD's if its even real.

scottlc · September 9th, 2003

There IS NO WAY to read a GD-ROM in a CD-ROM drive without serious hardware modification.

davv · September 9th, 2003

We all know cdrom drives don't read GD roms okay! Don't you think that he knows we know that, were not that f***ing dumb !! It will playoff cdr's backups or it's ISO. I say a 40% chance it's real without anymore proof. There are alot of people who sell these backups on the internet like for example *LINK RE-FREACKING-MOVED*

Regulus · September 9th, 2003

um.....isnt that illegal???

**Kane** · September 9th, 2003

/me repeatedly twats Davv over the head with the dumba$$ stick
you should really know better.

I'm pretty sure that it HAS been done with firmware modifications on the right drives. GD-ROM's use the same pit sizes as CD-ROMs, so you don't need a different laser, at least.

same pit size?
how do they reach then 1GB ??
some they have to crunsh not?

The link was not for downloading. It was for buying backups only.

Buying pirate copies.

Couple of theories I know of:

Absence of error checking data
On the fly compression

Regulus · September 10th, 2003

yes. pirated game backups.

**n_w95482** · September 10th, 2003

Supposedly it does have less error checking data on the disk. That's why those warnings are on the back of the cases (or so I've heard). It is easier to ruin the disk with scratches than a normal CD. For example, if you have X amount of scratches that are exactly the same that are on both a GD-ROM and a normal CD, the GD-ROM has a greater chance of being unreadable than the CD. I thought that the GD-ROM disks also required a smaller laser wavelength than normal CD's, is that true?
