Action Replay Won't Play Backups

[Shooman]

Mostly everyone knows how to play backups with an Action Replay - but just recently, I bought an old one (1997) Datel Action Replay (version 2.3) and the thing is, it won't play backups!
Your s'posed to stick in the copied CD once the orginal PSX CD spins down at the Action Replay menu....however, the orginal never spins down!
I'm completely lost.
