bootdisc dummy
 

Is there a program that will automatically make a dummy file for my boot disc which is in .cdi format?

Well, I'd say the subject is correct but in a different way... You're a "bootdisc DUMMY" :-)

Seriously, there is no need to dummy a boot-disc. Yes, it's tiny, but that's fine - just burn it and boot with it.

Yeah but it takes a long time to load and ive heard that you could burn out your dc laser if you dont dummy files.

Easier solution: convert all your nonboot games to selfboot. I did that in the past, but you can hardly find a non self boot game now...
