haha, oh wow

the DS section sure is impressive

hmmm can i ask some dl links for best PSP, Playstation And Playstation 2 emulators?

I don't really emulate, but last time I tried, PCSX2 (PS2) was ok.

For information, the PSP Emulator was very unstable and practically unplayable last time I tried it, which was only months ago, but I doubt significant enough progress has been done in such a short time.
As for PS1, you can try ePSXe and PCSX. They both work very well, one of them was recently updated too.

Emuparadise should have nearly everything you want, btw, otherwise Google can be very handy once you figure out how to properly search - patience is useful, too.

A second hand 1000 psp isn't all that expensive. Actually I think the Sony 8GB mem card is more expensive these days. >_> Worth it since homebrew is now as easy as pie.

PSPs are dirt cheap now. Plenty of second hand 3000s from casuals upgrading to a PSV, homebrew is as easy as pie these days.

pie

Use EmuCR to get them and to keep updated. As for the emulators themselves, JPCSP, the PSP one, still needs a lot of work, but you can play most 2D games (with the exception of anything done by tri-Ace) and a couple of 3D ones. PCSX2, for the PS2, has great compatibility (once again with the exception of tri-Ace games unless you brute force through them with a 2600K on software mode) but I haven't tried it for 6 months. And for PSX, you should go with PCSX, just make sure to get the plugins that aren't provided with the emulator.
