Thread: Custom Firmware 3.90 M33

3.90 M33-2

Requeriments:
- 3.52 M33-3 or higher

Instructions inside rar file.

Changes:
- Improvements in plugins loading code:
* Fixed some problems with problematic cards due to filesystem not mounted.
* Now plugins should read the faster.
* Problem fixed with lines with spaces at the end.
- Added the rest of regions to the recovery option fakeregion.
- (PSP SLIM): Added patches in nand ipl to allow Booster multiiplloader and TimeMachine iplloader to boot from nand.

Note: only 3.90 M33-2 and higher can be booted from nand in slim with those ipl loaders,
not official Sony firmwares or previous versions of M33.

Changes in updater:
- The 3.90 eboot downloading code is now more stable, no more freezes after selecting AP
- Memory stick write in the 3.90 downloading code is delayed the maximum possible for faster operation
(the system prefers big chunks of data written at once).

Just a word of warning: unless skype and/or internet radio is a high priority for you, DO NOT go beyond m33 3.71! Apparently sony has changed the memory stick driver in 3.80 and above to an inferior version which does not play nice with 3rd party brand sticks, notably sandisk. There have been many reports of games and/or saves no longer loading properly under the new driver where they were fine before. Dark alex has come up with a semi workaround by a patch which shoehorns his 3.71 driver back into the new firmware, but the process is too complicated for most casual users imo (and there are many reports of bricking as well).

Sadly i updated to m33 3.90 before knowing about this, and all my memsticks (sandisk 4 gig and 8 gig) have been affected. I can't run patapon for example, and emulators run noticeably slower than before. Thankfully the older games still work (though again noticeably slower). Just wanted to make sure you guys were aware before updating. If you don't need to, i strongly recommend you wait until this problem is resolved.

Being a novice @ the psp (only just got 1) i'm getting a bit worried, this all sounds scary.

Well, i am using 4GB Sony memory stick Pro Duo and it works fine with my PSP. I also tried the cheaper Sony memory stick manufactured in China and I don't have any performance problem with it. I never tried SanDisk memory stick and I could not tell how it really works with Custom Firmware 3.80 M33 and 3.90 M33.

As groundbeef says, if you're not very particular with skype or internet radio, Custom Firmware 3.71 M33 is just fine.

I'll try to search the internet and find out if there's a solution to the situation.
