Not sure if it useful to anyone not to sound like a noob but perhaps we can make more with it somehow?
Just look up Sega Blank GD-R

They appear on eBay sometimes, you can burn games on it with a Dreamcast development unit.

They're identical physically to high quality CD-Rs. The biggest thing that sets them apart is the media ID (same thing that tells your burner that a CD-R is rated for only 4x or 8x write).

If they are identical than why are high quality CDs only 700MBs? And GDs are 1.2 GBs?

CDs don't have individual spots for each bit to be written, it's just a coating. GD-Rs simply write the data closer together.

It's relatively similar to the difference between a 45 and 33 rpm record. A GD-R is just written to more slowly or whatnot.

They work almost identically to Double Density CDs, or the GigaRec format.

From what i heard, The CD's information spaces are farther while the GD-ROM Compacts that space to actually double the 650MB CD-ROM.

Do They still make these even?

but i wonder, if someone had a Katana Dev box and made an App in KOS, would it run? I know Dev boxes eliminated CD-R Boot.

anyway, nobody could relase katana software legally (make with Windows\DC-SDK)

I saw people mod Sonic Adventure with a Dev System. I wish I could do that :(

I think you can mod a ROM (without the Dev System), if you knew what you were doing.

I think that can be done with tools designed for specific games or the knowledge to manually mod games (which i dont have :( )
