Backup question

[Theaddres1]

Trying to backup Crash Bash.

The Original is working and playing on my modified PSX.
Do i need to patch it then ?
Or is it ok to copy it with CloneCD ? and then it has to work ?

As i tried that and it hangs at the beginning of the game.
Could it be a problem with the burning-speed or extracting speed as i read somewhere i think ?

I burned at 8-speed. is this too fast ?
