    Anyone else gone back to 4.01 M33?

    I was happily using the latest GEN firmware for a while but after reading that 4.01 M33 can also decrypt and play the newer games I decided to downgrade and check it out.

    Well, I don't think I will be going back to 5.50 now because as well as being able to play all the latest games I have noticed a large performance increase in memory stick speed. A couple of games that were laggy are now silky smooth. I had the fatmsmod patch applied to GEN but it didn't help all that much compared to now in M33.

    Plus I kinda missed having the 1.50 kernel addon. I know that won't be a factor to a lot of people but it still has a few uses left for some of us.

    So, has anyone else gone back in time?

    I'm on 5.00m33 and was postponing this as much as I could but now it's not really necessary any more, there's a patch for the games to work on cfw 5.0x.

    I doubt 4.01 M33 can play all the latest games, maybe the most recent games but what about the ones that were released a few weeks or months ago?

    Yes, compatibility is the same as 5.50 GENB2 for me, so all the latest games.

    hi people. i do not know if this is of any good but i noticed that there is still some problems between 4.01M33-2 and 5.50Gen gamesaves. they cannot read each other's game saves. so if i were to go back to 4.01M33-2 and later in a few months time got to upgrade back to 5.50Gen for whatever reasons, i may have problems with those game saves i had with 4.01M33-2. unless i missed some conversion patch or something like that, please point me the direction to do so. thanks n cheers!!

    Maniaczek switch to m33 driver and all must works fine.

    subcon959 couple games doesnt works fine on 4.01 . also Konjiki no Corda 2 Forte Encore doesn`t work at all on 4.01 !

    so 5.50 Gen is 100% compatibility . 4.01 - is 9x % compatibility.
    also most(or even all) new psn games goes with 5.05/5.50 key , so u dont need to decrypt eboot.bin separately , GEN can do it w/o ur help

    anyway i prefer 5.00m33-6 and i have a fat console with 4.01m33-2 also

    I'm not familiar with that game so not sure, but all games I have tried have worked ok.

    You are right about PSN games I guess it's easier to use version.txt, but at least they do work in 4.01 if you decrypt the eboot.

    With the new patcher for 5.00 released I might go back to M33-6 now too.

    motorstorm works too, but the savegame was created and encrypted with 5.00-33-6 so atm the savegame is corrupt

    What new patcher? I see that Eboot patcher, but isn't it the same thing we've had before? Or does it make it work for 5.00 M33?

    Hello people.
    My PSP has sat a box for a long time, however now with the release of GT and FIFA 10 I thought I would bring it back to life, I guessed I would need a firmware update but it seems I forgot pretty much everything.
    I am currently running 4.01 M33-2 what do I need or how do I get these iso's running.
    By the way thanks for any help.

    Well, 4.01 M33-2 will actually play these new games. You still need to patch them though.

    Take your UMD, rip the game. Rip out the eboot.bin using UMD Gen v4. Put the eboot.bin in the root of your MS. Download and install game decrypter v2 on your PSP. Run it - it will decrypt the eboot.bin. Replace the eboot.bin in your iso in UMD Gen. Rebuild iso, put on the memory stick, you're ready to go!
