How to make an image
http://imrtechnology.ngemu.com/tutdir2boot.htm I wrote it and it has pictures cant be to much easyer can it.? its fore the packman pack but you should be able to see what to do its all the same for every disk.


How to burn the image you created http://imrtechnology.ngemu.com/cdiburn.htm

Problem with asking is all info was there in the readme and how to burn was on my site. But its true if you dont understand or know how to make a SB cd then use the SBI's made for you at the other site. Vast amounts of people have used the 7800 mess build i put out and are waiting for the update and had no trouble burning it.

Case
You could also Burn it to a cdrom then swap it in using my bootdisk app. Make sure to unscrambled the 1ST_READ.bin.

Case
OR burn it to a multisession CD using nero. Then boot the dreamcast with demo loader and then boot the 1ST_READ.bin.
