Problems selfbooting MSR and others

[Excalibur007]

Hi,
I'm having trouble getting MSR and several others, like Sega GT, NHL 2K2, and more to boot.
After the Sega liscense screen, the game resets to the Dremacast screen, then Sega liscense screen, and on and on. It just keeps repeating the boot process.

I know this is a known problem, but I can't find a solution for it.
I have tried binhacking all the files with "CD001", but that doesn't work either.

I know there is a program to solve this, but it only works with the original .cdi file which I don't have.

I've wasted quite a few CD's trying this, and I hate hate to waste any more. Does anyone know how to solve this?

Thanks in advance for your help.
