Extracting file from games
 

Hello! I tried searching for this topic, but I couldn't find anything, so sorry if this has already been mentioned (but, if someone could point me in the right direction, that would be great)

Anyways, I want to extract some files from some PSX and PS2 videogames with my macintosh laptop. Problem is, they're ".EMI" files or something, and I'm not sure how to extract/convert them, persay.

Also, I don't want to *make* a game copy (but, if you know how to do that, then please tell me too! :D), I just want to look at some of the animation and backgrounds and whatnot.

If anyone knows of a cheap or free program to rip/extract files from a game disc, then that would be great!
