I see where you are coming from
There is a game menu selector in existance

, I have not tried it yet, but it was an early alpha test release. If you want it mail me through my profile and I send it to you.
I have asked around in the past a bit on some other dev/homebrew forums about the possibility of creating a DVD based game menu selector, or even modifying the existing attempt. No replies to posts
Even mailed the guru coder Sjeep (previous work includes PGEN & PSMS) about this but he has not returned my mail yet...
As I say, if you want to try it, mail me and I send it to you
