Well it looks like the original 8 wire modchip.com beta modchip is the little treasure enabling DVD-R backups to be booted.

Jumpstart - are you reading this? GT3 can be copied and booted at last! The wonder of the OrigaChip in these circumstances is that you don't need a JAp DVD original with which to supply the large TOC. That can be done with an import.

Now here's a suggestion for Datel: make a DVD-Backup-Boot "game" with the max TOC and blank stuff on it to enable legitimate backups to be booted.
