Je crois me souvenir qu'il y a des linuxiens sur ce forum, et j'aimerai connaître les outils et méthodes pour graver sous Linux des homebrew pour DC. Donc si vous avez des liens, tutos et conseils, je suis preneur !

j'utilise les outils de gravure standards
mkisofs et cdrecord et je suis parti de la doc de echelon
http://membres.lycos.fr/raptor83/dreamcast/download/e-selfbt.zip
J'ai fini par me faire un dossier et une doc plus adapte au homebrew

J'essayerai de penser a te l'envoyer ce soir

Merci, se serait très apprécié !
Ca m'énerve toujours de devoir rebooter sous Windows pour nourir la DC !

Bootable Dreamcast CDs have two sessions. The first of which is an audio track of at least 4 seconds (300 sectors) used for the audio warning when you place a Dreamcast disc in a regular audio player. The second track is a CDROM XA mode 2 form 1 data track (2048 bytes per secter). Interestingly, binaries loaded from CD-ROM are done so in a pseudo-random manner and must be "scrambled" in order to load correctly.

This guide assumes that you have placed the plain files in a directory named "data"

Create bootstrap
If the application that you are burning contains a file called IP.BIN, move it into the root directory and skip to the next step.

If you do not have an IP.BIN file then you must generate one yourself. Edit the information in the included ip.txt file and execute the following command.

makeip ip.txt IP.BIN


Determine your SCSI ID
The following command will produce a list of your SCSI devices. Take note of the correct value for the desired CD writer. In all future steps replace a,b,c with the SCSI ID of your CD writer.

cdrecord -scanbus
(cdrecord -scanbus -dev=ATAPI for ide burners)

Burn audio session

cdrecord dev=a,b,c -multi -audio audio.raw -speed 4

Scramble binary
If the Dreamcast binary is NOT already scrambled, you'll have to do it yourself.
The Dreamcast binary is usually called 1st_read.bin, if it has another name please substitute it in.

scramble data/1st_read.bin scrambled.bin
move scrambled.bin data/1st_read.bin


Find session offset
Execute the following command. This will return two comma-seperated numbers. Take a note of the output, you will require it later.

cdrecord dev=a,b,c -msinfo
(0,11702 for the default audio file)


Create data session image
To create the image for the data session execute the following command, substituting x,y with your session offset from the previous step.

mkisofs -R -l -C x,y -o data.iso data


Bootstrap data session image
Before you burn the data session you must inject the bootstrap (usually called IP.BIN) into the image you've just created.

bootstrap IP.BIN data.iso

Burn data session
Finally burn the image to disc using the following command. After this step completes you should be able to eject the disc and use it in your Dreamcast.

cdrecord dev=a,b,c -multi -xa data.iso -speed 4

Génial ! Je teste ça ce soir...
