by Mike Bendel on March 30, 2008 @ 1:37 pm


Homebrew developer Dark_AleX has issued an update to PSP custom firmware 3.90 M33 which further improves compatibility of the built-in M33 NO-UMD driver. As usual, the update can be downloaded from Network Update or by following the direct link listed below.

* March33 NO-UMD driver compatibility has increased to support games like Coded Arms, Patapon, Harvest Moon Innocent Life and probably others affected by same errors.

first , beotches .. going to install right now >.>

frosty5689 says:

does this update fix the reading off GAME390 instead of GAME380?

x3sphere says:

No, he forgot to fix that :P Still reads from GAME380.

frosty5689 says:

WHY!!! WHY!!!!-.- lol(not updating to 3.90 m33-3 then)

xiaoxuexue says:

哪有下载的说

Tenshigami says:

I'm more intrigued by the fact that he didn't make an update to popsloader yet so that 3.90 M33 can have the same features as 3.92.

As for the GAME380 folder snafu...Seriously. Is it really worth bitching about? I'm frankly tired of having to rename that folder every time I install a new CFW.

xkadajx says:

Does this fix the sleep problem on the fat psps?

frosty5689 says:

It means alot to me having a clean custom firmware(literally bugless). That's why I've been using 3.80 M33-5(for compatibility issues too).

Gwapingn8 says:

that's true...

i'm still stuck at 3.80 M33-5,

simply just like what frosty said...

it's bugless.... only problem I found is that

I have seen to lost the 1.5 kernel capability even after trying to install it back many times... and on all 3 times, they were installed well..

I wonder why? I miss my NES games.... =(

but it's ok.. GOD of War & Crisis Core is here. =)

B2K24 says:

Most everything goes in PSP/GAME anyway.....

whats it matter?

Thank you Dark_AleX

frosty5689 says:

I like the way it works w/ GAMExxx=P

JensenQ says:

who can tell me is it include Chinese Simplified language? I want update, but worriing failed language.

JensenQ says:

perfect!!! It's ok now. My dear PSP~~

PowerPrincess says:

what is GAME390/GAME380 for??

Acerthief says:

When we put homebrews in GAME3XX folders, it means we want the homebrew to be ran through the 3.XX kernel, not 1.5 or the kernel you've set for the GAME folder.

fire-ice says:

is it only the m33 no-umd driver compatibility is the only changes on 3.90m33-3?

or is there anything?

thanks for accepting me as a new member!

frosty5689 says:

The only thing that changed is the compatibility of the m33 no-umd driver.

RJC4LIFE says:

I did notice that the recovery menu loads faster now.So when you make a change it doesn't flash the screen when changing.it used to do that for me so I'm assuming something was changed..dunno.

And there's a 3xx version of NesterJ with rewind and mirror mode..I'm on the slim and basically all my emulators have been ported to 3xx at some point so I'm not missing anything due to lack of 150..Great job on the M33 driver Alexander...

B2K24 says:

The only thing I use that needs 150 is universal remote for my phatty and on slim the better SNES emulator is the snes9xTYL 0.4.2 that will only run under 150 kernel that can be launched using timemachine.

WhiteCrane says:

i never knew 3.90 had any no umd issues.

JonC04 says:

Well WhiteCrane, it didn't really have UMD issues, it just had some games that couldn't run without the UMD Disc. For example... Patapon wasn't able to run on the Memory Stick, and could only be run through UMD, but now it can run on the Memory Stick.

tekkai1 says:

yo, i updated it too 3.90 M33-3, and woah im playing god of war and its all glitchy, is there a way to fix that? like, im upset now =(

Evilredbird says:

any 1 got 3.80 or 3.90 official ? I need the file but cant find

daveth26 says:

My utmost repsect to Dark-Alex for his ingenius work. On the release of the update to 3.90m33rev3 via either patch update or wireless network update, these are successfully tested.

However, with regard to the creation of Pandora Despertar del Cementerio revision 5, I must say it does have very misleading implementation to the steps. After several tries, I affirmed Despertar revision 4.0 of 3.80m33rev5 works perfect with my proficient DOS commands. By allowing MSIPL.BIN at the root.

For the 3.90m33rev3, Dark-Alex has infused with Time-Machine changing MSIPL.BIN to IPL.BIN into TM directory. The main purpose is to work together in hand with Time Machine which nowhere was stated.

By generating the "kd" and "registry" from the pandora 3.90m33rev3, these must be restored to the root with the previous MSIPL.BIN to work without using Time Machine. These has been tested after several tries for the mistakes in the write up.

As what Alex has stated, MSIPL.BIN is the same.

Do note the above and perhaps update everyone concerning the sequence.

I have a japanese version PSP2000 , I've updated my PSP to CM3.9, skype was not included. I saw in japanese psp website, the delivered a update on 18 march with skype included, I would like ask how can I update my PSP with the new version.

x3sphere says:

There is no need. Just hold R during bootup to access recovery mode and enter Configuration then change the region to America. Skype should show up now.

skeith says:

dang... i have this problem too!

Everything just become 3! my date, nickname, MAC address, even my psp version also showing "3.33M33-3" What the hell is this! I CANT EVEN CHANGE THEM!!

I've found load times to be a bit quicker with the M33 driver. Might be just me though.

Reikasuya says:

When I updated, the wave in the background goes insanely fast. Why?

JonC04 says:

Dark_Alex(DAX) is the creator of the M33 Custom Firmware and March 33rd = April 2nd, which is todays date, and this is the 1 year anniversary of it, so this is DAXs little late april fools, your date will be 3/33, Name is changed to March 33, Mac Address is 33333333333, it's all just an Aprils fools thing, it should change back to normal tomorrow

Reikasuya says:

I turned on my psp everything except the wave was fixed; but then I turned it off then on and it's all good now.

3.90 M33 has supported popsloader since day one.

By the way, is source code for this program anywhere?

I was going to make a program and this would be good to base my code off of!

x3sphere says:

Crait: nope, the M33 firmware is closed source. Will likely stay that way as long as Dark_AleX continues to develop it.

crait says:

Haha, okay!

So I'm trying to patch from 3.52 M33-4, to 3.90 M33, but for some reason, when I start the 3.9 patch, it just says Unpacking... Done. Then Please Wait...

It's been sitting here for a few minutes like this. Anyone have any idea why? Or, what I should do?

psychomc says:

If you want to patch it from 3.52 M33-4 to 3.9

did you have the 3.9 Eboot in the root of the memory stick? If so , then run the patch

This can be resolved by choosing the Sony NP9660 Driver. Maybe DA will release 3.90m33-4 to fix this issue

kryptolite says:

Hi I want to upgrade to 3.90 M33-3 from my 3.71 M33-2 and I have downloaded the CFW from this website, but I read from the Instruction that I need Sony's OFW 3.90 to complete the upgrade. Now I looked at the Sony's website but they already have 3.95 instead of 3.90 and nowhere I could find a source that lets me download 3.90. Can I use 3.95 to upgrade to 3.90 M33-3? Or I should only use 3.90? If it is the latter can someone kindly share 3.90 OFW update file from sony?

x3sphere says:

No, you need to use the 3.90 EBOOT.

There's a download available for it in the 3.90 M33 install guide:

I updated my (fat) psp from 3.90m33 to 3.90m33 -3 but i didnt get any of the "april fool" things, also usb charge isnt show in the recovery menu.

what went wrong??:confused1:

please some help.

x3sphere says:

USB Charge is a Slim only feature. It's a hardware matter, it can't be hacked in on Phat units. For the April Fools, you need the date set to April 2.

Aaah .. thank you!

I was concerned something went wrong:blushing:

I update my psp for version 3.90 M33-3 and now i cannot run my PSX games !!! No run castlevania simphony of the night, resient evil directors cut and resident evil 3. But before update them run normal !!! Help me pls !!!

Sprangun says:

I realize that i update to the 3.90 m33 -2 (it was the latest at that time) and i dint get the skype program, does the new updates has it? Or the only changes is the no Umd thingy(i never had a problem with it).

x3sphere says:

On firmware 3.90 Skype is only available to US region PSP units so enter Recovery Mode (hold R while booting) and change your region to North America.

karabatak says:

someone please tell me how do i install it? i downloaded it. then... what?

x3sphere says:

karabatak: Assuming you are already running 3.90 M33 or 3.90 M33-2, just copy the UPDATE folder from the archive over to the GAME folder located on your memory stick. Then launch the 3.90 M33-3 update directly from the PSP's built-in Game menu.

darklingduck says:

Well X3Sphere, there are a couple of us that are new to the M33 world and would like to know how to do the initial setup on our PSP's so that we can use the software. The instructions refer to needing a PSP with the software already in it. I for one don't know anyone with it. How do I get started?

becoz says:

Hey,i have a problem here. When my System Software is still 3.71 M33-2,whenever i try to drag and drop the God of War CSO file into my iso directory of my PSP, i got this error "cannot copy GOW:data error (cyclic redundancy check) "

I have tried multiple GOW torrent files,but it all amount to the same error.

After that,i upgraded my System Software to 3.90 M33 via the links provided in this thread. I attempt to try to drag and drop the God of War CSO file into my iso directory of my PSP, i got this error "cannot copy GOW:data error (cyclic redundancy check) " again.

How do i solve this problem? I have loaded many games such as monster hunter 2 into my PSP without a sweat. I have tried restarting my PC,but nothing changes.

I have downloaded the fill onto my comp and I attempt to move it to my psp, but the file wont open alowing me to copy the update file to my game folder. How do I get the CFW to open on my comp so I can update my PSP

x3sphere says:

You need to extract the file using WinRAR or 7-zip... it's a compressed archive.

Is there any way to get thoughs without paying for them. Or is there a sertain 7-zip I need

x3sphere says:

Both are free... I prefer 7-zip though. Here's a direct link:

However,if i say that i have a God of war CSO,and i get this error "cannot copy GOW:data error (cyclic redundancy check) " even though i have System Software 3.90 M33,will you be able to help me? :smile:

x3sphere says:

Try formatting the memory stick, then copy the game back over and see if it works. If not there is likely a problem with your memory stick. A "cyclic redundancy check" error is the same kind of error you'd get if your computer hard drive was going bad.

If you copied the UPDATE folder to your GAME folder it shouldn't. Try formatting your memory stick and see if that helps.

I have a question and any help is appreciated.

I have a phat PsP with 3.90 m33-2 on it. before I put the 3.90 m33-2 on it i could play UMD games. Now I can only play games off my memory stick. Any help? If I upgrade to m33-3 would that fix the problem? I have tried changing settings and such by pressing R when starting with no luck. Once again any help is appreciated. Thanx.

MEandTHISarmy says:

k, got 3.90 m33-3 on there fine. Tried to bring over a few cso, worked for a bit, but then the unthinkable. They didnt work! lol. Well some work, they load up fine, i can play a couple levels and then always on a loading screen it will lock up. Patapon does it every time i try to go to one certain level, i can play others just fine, but not this one.It happens in Burnout legends as well. It goes to the loading screen then freezes and puts my psp to sleep. So i was trying to fix it and change the umd mode around. I got it on sony np 9660, which i heard worked the best. But now i heard things about turning the fake umd mode off, but you cant do that whilst using the sony np can you?

So what can i do to play these locking up levels?
