Use 3.71’s Memory Stick Driver Under Custom Firmwares 3.80/3.90 M33
greg | February 14, 2008
Update: v2 of the patch is available…
- 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.
Dark_AleX has released a patch enabling the memory stick driver from 3.71 on custom firmwares 3.80/3.90 M33. Why 3.71? Its fatmsmod.prx just plain old works better.
Instructions:
- Use psardumper to grab ‘fatmsmod.prx’ from 3.71; encrypted or decrypted
- Copy /F0/kd/fatmsmod.prx to the root of your memory stick
- Copy FATMSPATCH from this package to /PSP/GAME and run it
Few things to note:
- it’s probably a better idea that fatmsmod.prx is encrypted because it’s compressed and uses less flash space
- fatmsmod of 3.71 usually works better because it has a better cache system, and usually reads on bigger blocks (sometimes 3.80/3.90 reads more data than needed — lazy prediction)
- however this driver uses more kernel memory, and it’s unknown if it will have any kind of secondary effect running this module in 3.80/3.90 — use at your own risk
- the lags in np9660 no umd mode won’t probably be solved, as that is a different problem

Sweet!
Will this fix my PSP (that is running on 3.90 M33) ’s inability to write new save files? Cause thats really pissing me off. If anyone knows how to fix that, please let me know. e-mail me at a_memory_better_left_forgotten@yahoo.com
so waht’s it do again? waht’s it’s purpose of existence?
Learn how to spell what you faggot.
it’s so we can have the normal/faster xmb speed of 3.71 in our 3.80/90 cfw, as oppsed to the “slower” and or “lagged” speed of 3.80+ firmwares.
i’m pretty sure that sums this patch up.
i haven’t done it just yet, has anyone tried it ?
if so, is there a noticable difference in speeds ?
i’m sure it does work, but i’d like to hear some feedback before i do it.
it works fine but be warned
you can’t see your videos,music or
pictures anymore
as far as fixing the mem stick lag
works well
“so do this at your own risk”
my psp has bricked with this…
how? it doesn’t mess with the flash0/1. So, just delete the prx from your psp, and fix the txt file, and it should be fine.
It’s not a plugin, it does write to your flash0. Have you done it yet? Because if you did you would know that. By the way, it appears to have semi-bricked mine too. I’m using the sleep-fix multi-ipl installed by upms. I’m still able to get into both recovery mode and the pandora menu. But the xmb won’t boot.
Version 2 works for me! Just sucks I had to pandora back to fix it. Re-entering my static IP is a major pain. Yay DaX! He actually fixes things in a timely fashion.
full of bull!!!
Whoa this stuff is great,game speed is like before but like Oi8U2 said it will make your videos,pictures and music not work anymore make sure somebody create there flash 0 backup
For people who’s curious about my current firmware only!! psp slim 3.90m33-2,yes it does writes to the flash O,wonder if dax found the problem for MS patch 3.80/3.90m33
there is a version 2 of this update
at dark alex org and all works fine now
everything is awesome
3.90m-33-2 now smokin
I haven’t noticed any slowdown since 3.80 and 3.90, but if there’s a patch, I guess DA acknowledges it.
Please help me, Please teach me the step by step procedure. please someone provide the ‘fatmsmod.prx’ from 3.71; because i can’t manage to download the original 3.71.pbp because I have a dial up connection. thanks
Only for you, noobie.
Download it: http://rapidshare.com/files/91799958/fatmsmod_v2
.zip.html Copy in same directory and install
It’s Version_2
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.
Note: please read coments before installing
Sorry linnk already dead try this

thanks
As it appears, staying at 3.71 CFW is better than upping to 3.80 or 3.90 CFW which I will do…
You absolutely right +1
Yeah If you Fat user.
Is this patch for the slim psp?
I’ll stick to my 3.71, There is nothing special about 3.80 or 90, Now if sony comes out with a cool new FW that enables you to use the PSP on the TV or something, or anything better then a Online Radio, then I will update to a new FW, until then, 3.71 is the best.
get a slim it allows video out on your tv and with 3.90 you have skype functionality
fatmsmod v2 can´t read non-unicode :(
Does this work for slim? I haven’t noticed any slow downs on plugins or whatnot on 3.90 M33-2
Thanks Russian_man for the megadownload.
After updating to 3.90 M33-2 my 4GB mem card could not be used at all (Formatted to fat16 to speed it up). I had to use my original 32MB one to apply this patch to get it working again. Now all iso and movies work as they did in 3.71 M33 on my 4GB card.
Does this work on psp slim?
Before this patch I seen no problems, or slow downs on 3.90. I used and I still see no difference.
There also seems to be no one that can clearly explain what this is supposed to do… I keep hearing it makes the MS read faster, but where… on usb, in game?
It seems pointless atm.
ok fucking answer the question, does it work on the psp slim?? goddam, u see people asking so answer the fucking question dipshits.
Dont do it! it has alot of problems with mp3s and wma long file name even I used v2 but still no go:(
Yes the 3.8 and 3.9 fatmsmod.prx run ISOs with hickups but very smooth with 3.71 so that is why DA try to replace it with the one in 3.71
i’ve read it does work on the slim aswell.
i think it’s worth doing if your MS is slow like most peoples in 3.80+
i’m going to do it later, can’t wait to see the speed difference.

Why go through all this Fuss ? why not just stick with 3.71. What Great Almighty thing’s does 3.80 and 90 have to offer ?
Use my dick Under Custom Firmwares 3.80/3.90 M33 DAX!
the slowness can be fixed by using error checking on the memstick, it fixed mine when i first got 3.90m33
before installing this… GTA wasnt working. But its working fine now after intstall :D
Can someone please upload the working fatmsmod.prx somewhere else not megaupload i’ve had problem with mega cause the slot for my country are full try sendspace
I will be very thankful
Sorry i had a connection problem can you guys upload the working 3.71 fatmsmod.prx to sendspace and other surver not megaupload
I still don’t see any speed increase after applying this patch. Although it does give the impression of only workable on fatpsp and possibly on slim as mentioned above, it only really says it speeds up plugins for some users experiening lag when loading compressed files and plugins from the memory stick, an issue that did not exist in previous firmware releases so it says.
The patch allows users to load the original 3.71 fatms driver on 3.80 and 3.90 M33 series firmware, which if installed, will resolve this issue.
So basically increased memory speed with increased kernel memory. Another guy above mentioned 4gb not working after update… I use 4gb Sandisk MS PRO and still haven’t seen anything wrong. I think it’s solely for Phat users than Slim users since I myself use a slim.
I’m waiting for the fatmsmod.prx @orly if you have winning eleven pro evo soccer 2007 in cso format try to compare with the 3.90 with 3.71
this dose work on both psp fat & slim.
although not realy needed with slim but fat it is.
to me 3.90m-33-2 works as good as any other cfw.
have used all have both psp’s i have no problem with 3.90 at all there is some kick ass themes out now. no reason to stay behind skypes pretty kool as well thanks DA awesome
thank you dax
Sorry,this patch is a bummer. Have tried both encrypted and decrypted prx files and still NO pictures,videos,music even after reformating MS. Cannot download content. Maybe has something to do with the NIDS when OFW3.80 came out. Back to CFW3.90m33v2 via Pandora. Goodby Yellowbrick PSP. Peace
did you use version 2 as i had this problem
with version1 but 2 is fine all music, video and
pictures are back and all is sweet
can now put cpu back to default runs smooth as
If you foreigners dot’s forget! Via this patch all music & videos must’be rename on english. Onter languages doz not SUPPORT!
SoRrY fOr my BaD EngLiSh ))
I semi-bricked my psp installing this. I thought I did the sets correctly, but I guess not. I do NOT have a Pandora battery nor the UPMS. Is there anyway for me to use the recovery menu to fix my problem or did I shoot myself in the foot?
Yeah … I did the same thing …. and when I try to fix it by putting back in the old fatmsmod.prx back in it wouldnt even turn on … but I did have a phat psp battery to unbrick it. if urs is screw up … try to make a pandora ms and when ever u get ur hands ona phat psp battery just pandorize it unbrick ur psp and just turn the battery back to normal. ….
ps; I know there no such thing as a stupid question but a stupid person that ask it … if I were to give u all the files in my flash0 and u use it to replace the ones in your psp flash0 would it work? just wondering
you can downgrade through recovery. whats your firmware version first
works great! now vcs runs without hiccups on my sandisk 2gb(slim psp)
My Version is 3.90 M33-2. I try to keep it up to date with the lastest CFW. I knew this might happen one day, but never got around to making a Pandora MS/battery. Looks like now I have no choice in the matter :-)
I have 2 psp’s one at 3.90 M33-2 and the other 3.80 M33-5 and I’ve noticed a difference in speed with games. Mainly with my TA-086 PSP (3.80) it cuts off on its own and sometimes the power button does nothing. I don’t see any speed difference with my 3.90.
great peice of work imo a must for those using psptube that save the vids to ms for offline watching.. i noticed though that it can actually slow down worse if you use the uncompressed version of the file for patch. best bet use encrypted no sigcheck you can really tell a difference running stage6 vids from ms
opps forgot to mention using a slim and this works fine on everything i run.. maybe with TM you could do the 2 different options. hold – on boot = 3.8/3.9 fatmsmod.prx, hold + on boot = 3.71 fatmsmod.prx. and always remember to expect a possible brick on every single flash write even the ones you have done hundreds of times (batteries can come loose, psp’s drop, ect.)
my psp with cfw 3.90 m33-2 works very fast with this. just follow this procedure:

i forgot to mention my psp is a slim type 2006
HMMM had lags with 3.80 but no lags or glitches on my psp slim with 3.80 i think this isnt needed for 3.90 at all!!
if you timemachine your psp you can use your pandora battery to boot to the xmb with your normal memstick no need to convert back anymore yay
