is there a dreancast emulator? no right ?
if so does any 1 no where i can get every thing for it
so i can play my games?

Check the ngemu news.. Icarus, a dreamcast emulator, is currently in the early stages of development.. And no, there is no dreamcast emulator that can fully play commercial games yet.. Dreamcast games are on proprietary GD rom disks which are mostly unreadable by regular cd rom drives or dvd drives..

so that only means you have to wait and buy the GD rom which is about the same price as a DC

i got a dreamcast but im just always on my computer so i thought that i could play them on my computer

Just buy the console, for all you people waiting for an emu. If you save 2 dollars a day while waiting for it, you'll get a dreamcast with some games in 2 months.

Dvd players? Or dvd drives? My dvd drive can only read the outer track on the gdroms because some of the gd rom disks are made to be readable at those places but not where the game data is.. GD rom disks are not like cd rom disks or dvd rom disks.. You'd need a special cd rom drive to read them totally..

Here is some info on GD rom disks.. :

The Sega Dreamcast CD's are actually GD-ROMs, sort for Gigabyte Disc, holding maximum 1 GB of Data instead of the standard 650-700 Mb. Developed by Yamaha, the GD-ROM is a proprietary format which works by packing the pits on the disc closer together to store more data. Along with more storage the GD-ROMs provide an extra level of Copy Protection as they cannot be reproduced using a standard CD-Writer.

The are 3 distinct area's when you look at the bottom of a GD-ROM disc.
The low-density inner track (dark gray) contains about 35 Mb (4 mins) DATA which is also accessible by normal CD-Readers.

The outer track (light gray) contains about 1 Gb (112 mins) DATA but is written in a high density format which can NOT be accessed by normal CD-Readers.

The area between the two tracks (black) doesn't contain DATA and acts like a border. In this ring the following texts can be read:
Produced by or under license from sega enterprises LTDs
Trademark SEGA
A normal CD-Reader will only read the first, inner track and won't read past the black area. Even if it could read past the black area then it can't read the high density track.

The details of the high-density region really aren't known, but there are two popular hypotheses. The most popular is that the high-density region has minimal error correction information that's even worse than regular CD audio. Support for this can be found with Sega's unusually excessive warnings on their discs "Handle with care. Scratched discs will not play." Unfortunately if that were true, then all of the discs at Hollywood Video would be broken. The other hypothesis is that the data is stored in CAV/CLV format much like laserdiscs.

just wondering...if this is so, did Cyrus64 test his emu by making an iso on his computer via his programming cable connected to his DC?

**fivefeet8** · June 15th, 2002

can NOT be accessed by normal CD-Readers.

Maybe a modified cd rom drive can.. I also wonder how cyrus did it.. Iso? or Modified cd rom drive?

**CyRUS64** · June 15th, 2002

fivefeet: gdrom format isnt as 'custom' as sega would like people to have believed... yes, it is technically possible for certain cddrive units to read gdroms but tbh I dont think we are going to see this ability for quite some time if ever. For my testing, I just use a bba w/custom dumping s/w to create images of gdroms and then burn them to cdr, and boot from the cd-drive. Alternatively .iso support is available...

**cooliscool** · June 15th, 2002

all drives can read the outer layer.. its just iso9960.. the low density area, since yamaha made the gd-rom it's been said certain yamaha drives can read them, but i dont think any DVD drive can, ive heard that theory alot, and it clearlyt is not true, as my samsung dvd sd-608, only reads the low density area with the txt files saying for use only in dreamcast

btw, cyrus, do you play pso?

*runs out and buys a yamaha cd-writer

**CyRUS64** · June 23rd, 2002

cooliscool: no, I haven't had the money to buy pso and since I dont usually have time to play games for too long anyhow...

JuniorCRB · June 24th, 2002

Hm, you know the best part about NGEMU is it's where both authors and leechers hang out.
