Well as you all know converting PSX games to ebooot will work on a PSP,but what if you convert a ps2 game img file(if there are) to eboots?will it work or not?
The reason ps1 games work is because it's using the built in emulator for ps1 games, the games are just converted so they can be read. Ps2 don't work because the psp hasn't got a built in ps2 emulator...and it's a tad weak to even emulate it....though there are prototype dreamcast emulators...well only one but it was made in the hope someone would take the P.O.S that runs less than 00.4 fps. I seen the vids...needs ALOT OF WORK!!! Short answer-psp can't do ps2 no matter what.
