No, it's not a dumb question. Certainly CloneCD will make an EXACT copy of whatever you throw at it, provided your CD writer is compatable.
As far as having a Playstation chipped or modded, then yes, I think you have to do that too. I don't have a PS though so maybe someone else can answer that part for you.
Any CloneCD questions you have feel free to ask me at
[email protected] and I'll try to answer anything I can for you within a day or two.
