(Modification to title: How do i copy a backup (selfboot and non-selfboot) dc game?
For sum reason, i can burn a dc selfboot game (mainly im trying to burn nba 2k1 and nfl 2k1 right now). But when i test it out on the dc it doesn't work. It just takes me to the cd player screen. The burner i have is a:
IDE-CD R/RW 4x4x24 (it came with the computer)
The programs i use are: Nero v.5.0.4.4 and CloneCD v.2.8.4.3
I have a pretty fast computer. Its a 700mhz w/128 mb ram.
Can sumone please help me? Thanx.
