Personally, I'll still be waiting for someone to release a homebrew Playstation emulator, as we all know that this POPS emulator contains copyrighted code... so distributing it is probably actually not too legal (Even though they pulled the plug on it).
Not to mention that it isn't going to be easy to fix the bugs that it has, although it's already quite good.
Offtopic: I've sent you a reply about your GBA emulator a few days ago. Did you get it?
