psx emulator

where do i find this ps1 emulator...and is ISO same as rom? confused. please help, thanks.

what kind of emulator....for pc, for a console, or for something else, as for roms, rom is a short term for saying the game was ripped out of the original game file, cd....and I think rom isnt the same as iso.....iso is the format that the rom came as....., or in diff formats which ever comes.........they just call it rom because its no longer playable just for ps1, it can be played by any system, thats what I believe.

in this case, rom and ISO are the same. Technically they are different, rom = cartridge, ISO = disc

aahhh...in that case, I was totally wrong, now we know...;D :P
