PS1 in the Palm of My Hands

I've never owned a PS1 before, and now the PSP is letting me play on all of the games I missed out on. After a bit of hard work, I've been able to upgrade my 2.81 PSP to 3.03 firmware, then downgrade it to 1.50 using an exploit in GTA Liberty City Stories (which I had to buy in CEX) and then upgrade it again to a modified 3.10 firmware. This lets me play any Playstation 1 game which has been suitably converted for use on the PSP and also any other games I happen to "acquire" over the net without any fiddling about. It's really quite awesome. Now I just need to get hold of some PS1 games as the net's proving to be a bit of an unreliable source for them. I may have to raid tktiger's collection sometime soon :D
