Playstation 1 ISO Emulator for the PS2?

Hi,
I was wondering is there a playstation 1 emulator that runs ISOs off a disk or a usb device? cause i got modded ps2 but it doesnt play ps1 games anymore..

thanks

Dude this is the PSP emulation forum I would put this in the Sony game consoles and hardware forum or whatever it's called.

oh crap wops, sorry about that

ePSXe probably the best Playstation emulator for windows. Try google next time.
