    psp 3.71 fatmsmod patch released V2

    News from Dark Alex

    Patch to load 3.71 fatmsmod in 3.80/3.90 M33
    The purpose of this patch is to load the fat memory stick driver of 3.71 in 3.80/3.90 to make memory stick reading work better.

    Instructions:

    - Using psardumper get fatmsmod.prx from 3.71. It doesn't matter if it is decrypted, encrypted, etc
    It is probably better idea that is encrypted because it is also compressed and use less flash space.

    Copy it from /F0/kd/fatmsmod.prx to the root.

    - Copy the FATMSPATCH to /PSP/GAME and run it. If the patch is successfull, you'll have 3.71 fatmsmod running in 3.80/3.90
    This process flashes the fatmsmod.prx as flash0:/kd/fatms371.prx, it adds a custom file needed to compatibilize the module with 3.80/3.90 (fatms371_friend.prx),
    and changes the pspbt* files.

    Note: fatmsmod of 3.71 usually works better because it has a better cache system, and usually reads on bigger blocks.
    (in some things is worse than 3.89/3.90 like sometimes reading more data than needed - lazy prediction -).

    However it uses more kernel memory, and it is unknown if it will have any kind of secondary effect running this module in 3.80/3.90

    The lags in np9660 no umd mode won't probably be solved, as that is a different problem.

    Changes in v2:

    - Added to the installer the check of correct checksum of fatmsmod.prx. Use only encrypted or decrypted version of file.
    - Music, videos, etc now work.

    That actually appears to be fixed as well. At least with some games. What kept me from upgrading my Slim PSP was that playing games like WipEout Pure and WipEout Pulse backed up to .CSO caused a sporadic jerky sort of lag when using np9660.

    Now that I have applied this patch I am very happy to see that both WipEout games seem to now play just fine. I haven't tested too many games yet and we can't turn this thread into an ISO or CSO compatibility thread but it so far appears that the issue is fixed.

    I am very impressed with this patch.

    Good news!
    Looks like there is no reason not to try out 3.90 for awhile.
    Good thing Pandora makes it very easy to go back to my custom 3.71 if I don't like it.

    This is cool. I don't have any problems problems with 3.80mm3-5 on the phat but this should help some people.

    has anyone else had this problem?

    i noticed lastnight after installing the patch a few days before that most of my mp3 files dont show up in music. i did a diagnostic just and it was the patch causing the problem. i have a 4gb sony stick, i assume that the patch is only to be used if you have a 8gb stick OR this is a actual problem.
