    sorry to burst your bubble, but compressing ps1 games to that amount of level will probably render them unplayable, at least i have not tested, i have "lag spikes" when playing metal gear solid when im compressed disk 1 from 650 to 480.

    not worth it, only compress it slighty imo.

    they're probably missing sound and stuff, to do that u need to use ps2dvdgen or some crap, it's a pain in the arse. cuz u basically need to rebuild the entire game, dummy files etc. etc. similar to using UMDGen but it's a bit harder IMO, as stuff back then wasn't labeled as well :)

    nah, its easily possible, depending on what you're taking out of the game (like FMV)

    i'm talking strictly about the file structure and naming of them is wierd for certain games. so it can be tricky.

    plus certain games just can't be done. (atleast not that drastic a change)

    nevermind, i'm talking about rebuilding the game. removing FMV/Audio from certain games would be too difficult for a n00b to grasp. not to mention keeping LBA's and structures and things of those nature. There are guides on how to do this, but it is time consuming. and like i said certain games would need more then just a quick rebuild.
