    the memory speed up option works great for me. I have it on always.

    you can try looking for an iso of the game, might be a bad compression job
    The only cso I use is the ones I do myself

    Try changing the ISO loader you use.

    Usually from recovery menu (press R and hold while powering on PSP). With PRO-B you can change it by pressing Select button in XMB and restarting PSP after change.

    There was a thread iso vs cso which pretty much covered that some games just doesn't work that well with cso format and some doesn't have any problems. If you get some loading issues with cso files I recommend to convert it to iso or get clean iso version. It takes some more space but It's usually much faster. Cso just doesn't work that well becouse it's compressed and iso isn't.

    UMDGen is handy tool. You can delete /PSP_GAME/SYSDIR/UPDATE from taking space, search dummy data and save your cso files to iso format.

    Ok. I have the list of options here.

    1. If you have a 1000, use fatMSmod if you're on a 5.XX CFW. It will make stuff run faster.
    2. Update to PRO-B8, NAO. use the memory stick speed up option, it does WONDERS.
    3. Decompress it and use the .iso. [​IMG]
    4. compress it at a smaller rate, or use a different program. Not ALL programs work properly (UMDGEN is usually choice).

    I am pretty sure that's all the options you have. NOTE some games CAN NOT be compressed and still work right. Like games with lots of CG cutscenes or constant loading... it's too taxing on the MS for it to have to do extra work. Kingdom Hearts BBS and DJ Max series are examples. DJ Max lags to a point of unplayability under certain conditions. Some games, like Patapon, run great as a CSO. Smaller games tend to work better than larger games as CSOs, for the most part.

    I can confirm the following games run fine (no lag, just slower loading times) as a CSO:

    *Monster Hunter (series)
    *Patapon (1,2,3)
    *Gitaroo Man
    *Persona 3 Portable
    *Persona

    I can add more once I check my list again, if you want more suggestions.

    like to also note that when copying files over to the memory stick the speeds are slow at 3MB a sec. Even my micro sd cards i have are twice that fast.

    CSO's are bad. But it sounds like your MS is awful....run a PSXReality Speed test and check the results.

    And for reference the fatmsmod.prx swap shouldn't be done on 5.00M33-6 as the built in MS speed up works better and isn't mutually compatible.

    I agree with xist. It sounds like your MS is the culprit. Just booted up my Patapon 2 cso and it took about 15 seconds of loading to get to the menu screen.

    Also it may be an idea to check you haven't altered the Game Clock Speed below default.
