Hi everybody
As my title suggests im a total novice and am seeking your wisdom and advice.
Simply how do i burn games.
Ive download various programs, that burning websites have suggested, im just wondering what i do next.
ive got
Nero
Diskjuggler
Winrar
Fireburner
Isobuster
Cdrwin
Dummy file creator
and lots of guides that make no sense
ive downloaded a number of dreamcast game roms from kazaa. so ive not had a problem finding games.
I also cant find a guide on how to burn directly from a disk to a cdr, is this because dreamcast disk are gd roms? and if so is there a way to extract the files directly from the disk. (ive heard of ripping software)
Anyway if anyone can give me advice, or suggest any websites that help, plmk
Thanks for your time
Darren
