    I got a PSP a couple days ago and istalled custom firmware with Lumines.

    1) I heard that compressign ISO's will make it lost some sounds and other things. True?

    2) How big are ISO's, because I bought a 4GB Memory Stick PRO Duo, so if that is big enouygh, I'm not going to compress the ISO's

    If you have a 4GB stick then you don't really need to worry about compressing them. My friend has only a 1GB stick, and he can always fit atleast one full sized game at a time.

    The first one is wrong. Compressing ISOs will rarely cause problems with a game and at most increase loading times a tad I believe. Ripping ISOs is what you are thinking of. That is when you literally remove files from the iso to reduce the size. Such files could be extra languages, update folders, videos, multiplayer content, music or quite literally anything else you don't want/need in a game, provided the missing content does not cause crashing of course.

    And ISO sizes vary. The maximum size is around 1.8GB but many do not go over 1GB. So a 4GB stick is plenty.

    Metal Gear Solid: Portable Ops ISO size is 1.29 GB

    There's a couple more titles I saw a while back but I forget what they are...

    DJMax Portable 2 CSO is 1.52GB
    Untold Legends The Warriors Code CSO is 1.23GB
    SDGGeneration Portable, CSO is 0.98GB
    Gitaroo Man Live Europe CSO is 946MB
    Also there are several games that are CSO ~900MB

    1GB MS has capacity of 900 some MB, it's unwise to try 980MB game in there.

    Back to on topic, I made all my ISOs into CSOs, hoping I can stick in another game, but really didn't happen. On average you'd have 5~6 games in your 4GB MS. I'd say that's just barely enough number of games to have in my PSP. (Well at least one UMD game will be in my PSP to increase by 1)

    edit: forgot to say 4GB

    Well, totally depends on what games you play.
    I prefer full over rip, but still I can stick 18 (theoretically could go over but I don't have small games any more) games in my 4GB or I can max out after putting 3 games, really depends.
