New person needs help

[Tha Shiznit]

I need to backup some cds, but i`m confused about some conflicting things i`ve read on here. I copy audios with Nero, and i can backup any psx game with Clonecd my Ricoh cd/rw which handles all the subchannel data and Raw DAO stuff.
PC games seem a bit more difficult- do they always have to be patched or, as i read on here, can a 1:1 copy be made and played straight out.
The games i want to backup are Operation Flashpoint, Commandos 2 and Desperados.
If anyone can help with patches and what to do with them, which ones to use and how and when to use them, it would be very helpful.

Thanx
