I don't think Dark_AleX or anyone else will go out of their way to try and inject their own code to modify SONY's POPS emulator.
There are indications that SONY may at some point implement ad hoc for PS1 games and I think it is better to let SONY add that feature.
If ad hoc can be implemented into other unofficial emulators, I'm confident that it is possible with PS1 games.
I know I will be upgrading to 3.30 OE immediately as I really could care less about custom icons which seems to be why a lot of people stay on 3.03 OE-C.
