Prometheus-3 for 5.00 M33, 5.03 GEN-C and 5.50 GEN-D3

For those looking to play the latest PSP games that require 6.31 OFW on your favorite custom firmware but can’t due to the new firmware requirement, Chinese hacker liquidzigong has updated his Prometheus module to Prometheus-3.

Now if you’re not sure if what this add on does, here’s the changelog:

Improves the compatibility of CF with the latest games that require the official firmware 6.30/6.31

Important Note: Prometheus-4 is now available for people who want to play Monster Hunter Portable 3rd.

Important Note: This release is currently Prometheus-3 v2.

Here’s the Prometheus-3 add-on for each of the popular CFW for the PSP:

Prometheus-3 for 5.00 M33

Requires: 5.00 M33
Download: Prometheus-3 for 5.00 M33

Prometheus-3 for 5.03 GEN-C

Requires: 5.03 GEN-C
Download: Prometheus-3 for 5.03 GEN-C

Prometheus-3 for 5.50 GEN-D3

Requires: 5.50 GEN-D3
Download: Prometheus-3 for 5.50 GEN-D3

Please note that you need the required firmware to be installed before getting the modules on your PSP.

To install:

  1. Extract the zip archive for your custom firmware
  2. copy the Prometheus folder into X:PSP/GAME/ (that’s your Memory Stick)
  3. Run the installer from the XMB and then hit X to start the installer

If you’re already on the Prometheus module, simply follow the instructions above and it will overwrite the Prometheus module installed on your system.

    1) Ano po yung mas latest? Itong Prometheus-3 v2 or 5.03 Prometheus v4?

    2) Ano po yung mas recommended niyo na ilagay?

      Mas bago ang Prometheus-3 v2, Prometheus v4 is version 4 of the original Prometheus module

    i have 5.50 Prometheus v4 right now.

    how to install this new Add-on?

    • sylv3rblade November 12, 2010 Reply

      Just follow the instructions, it’ll overwrite the old Prometheus module you have installed.

    does it support homebrews and plug-ins specially game categories? what about pops? oh and emulators too. Are they all supported? btw im using psp3004 5.03 gen-c! can it play spectral vs generation [eur]? thanks for taking the time answering my questions.

    Does Prometheus get deactivated when the PSP is fully turned off like in GEN-C?

  6. kathy025 November 16, 2010 Reply

    I found my answer to my own question, yep, once the PSP is fully turned off, you have to undergo:

    ChickHEN R2 > 5.03 GEN-C > Prome-3 v2

    Not that it’s bad though, I actually prefer the ChickHEN method over the permanent CFW because theoretically, it’s impossible to brick the PSP3K with ChickHEN, unless of course you do something stupid. 🙂

    • sylv3rblade November 17, 2010 Reply

      Yep but the advantage of a permanent CFW is that if you get bricked, there’s still a Pandora battery to save you :).
      Kudos to your successful installation though 🙂 Enjoy your PSP 🙂

    Hey, I just upgrade it following your instruction. Thanks to you, I can play all games I can’t play on GEN-D3. Now the problem is, before I upgraded to Prometheus and can play DW: Strikeforce. After I upgraded to Prome-3 I can’t play Strikefore. Help?

    • sylv3rblade November 17, 2010 Reply

      That’s the usual problem with the PSP’s cfw scene, incompatibility with older games.
      Instead of trying to downgrade, either look for a PATCHED version of DW:Strike force or download a copy of ISOTool and patch it yourself.

      Oh and v4 is out. I might as well update the links 🙂

    so if mine PSP wiht 5.50 Prome-2 i need to upgrade it to prome-3?

    • sylv3rblade November 21, 2010 Reply

      Only if you want to play games that don’t currently work with prome-3 (newer games that is)

    Crap, liquidzigong has quit the PSP scene due to legal issues with SONY and CAPCOM.

    sir pa update naman lahat ng links gen d3

    thanks sir

  12. bdcm26 January 13, 2011 Reply

    which is better prome-3 or prome-4? is prome-4, same as prome v4? confusing… tnx..

    • sylv3rblade January 13, 2011 Reply

      You can think of Prometheus v4 as version 1.4. Prometheus-3 is 3.0.

    • kathy025 January 29, 2011 Reply

      “Is prome-4, same as prome v4?”

      I believe Prome-4 is Prometheus 4.0 (the version after Prome-3v2) and Prome v4 is actually Prometheus 1.4.

      Heck, I wish Liquidzigong would’ve stuck with Prome-1.4, Prome-3.2 and Prome-4. Makes things a lot less confusing. XD

      • sylv3rblade January 29, 2011 Reply

        Yes, that is actually the case. Prome -4 is Prome v 4.0 and prome v4 is 1.4

        • kathy025 January 31, 2011

          Haha you should include that explanation in your Prome articles Sylv3r. Lots of people actually get lost in the Prome version names.

  13. Lloyd January 23, 2011 Reply

    which is better? 5.50 GEN D3 or 5.50 Prome-4? and what’s the difference between those 2?

  14. kuya lei February 20, 2011 Reply

    so yung mga plugins ng 5.50 GEN-D3 ay compatible parin po sa Prometheus 3?

    such as: screen capturing etc..? tama po ba?

    • sylv3rblade February 20, 2011 Reply

      add-on lang ang prometheus so it won’t interfere with other plugins.

  15. Kazuma August 16, 2011 Reply

    I have psp 1000 5.5 gen-D3 (PHAT) so if i upgrade to prome-4, would all my games still be working as they were on gen D3? what kind of add-on is it?is it better?

    • sylv3rblade August 16, 2011 Reply

      Prome-4 is basically prome-3 patched to work with Monster Hunter Portable 3rd so yes, your games will still work.

      • Kazuma August 17, 2011 Reply

        1 more thing. is gen D3 somehow related to prome? it was said that prome can be called like gen D4 i’m not sure. and looking at the previous posts, wont it cause incompatibility wif other older games? quite confusing… pls help. nid to confirm as its a bit of long process to use pandora and magicstick to change back.

        • sylv3rblade August 17, 2011

          The prometheus module is an add on to permanent CFWs. It’ll allow you to play games that require 6.xx OFW and above.

        • Kazuma August 17, 2011

          sounds like it wont affect the game compatibility of the previous cfw before installing prome 4….since like u said its an add-on… am I correct? thx for the help.

        • sylv3rblade August 17, 2011

          The only possible problem is if you decide to upgrade (to 6.xx) in the future as you may end up with corrupt saves but not to worry, we have a fix for that.

        • Kazuma August 20, 2011

          If it is like tat then thx. I’ll consider about the update since i’m afraid save files won’t work & i would have to hunt for the fix like gen d3. & since yoshi left the psp scene too, there wont be gen updates anymore do i gotta change so tat i can play games requiring high firmware.

    sorry guys I am so newbie here and just installed everything. I have loaded an CSO game in my MEM:/PSP/GAME/ and yet it’s not loading. anyone?

  17. Darkslayer November 16, 2011 Reply

    Sir question lang po. If gamitin ko po ba yung Prom add on magagamit ko pa rin yung mga saves ko for older games like dissidia012, disgaea AoD? Possible pa rin po bang bumalik sa older firmware after adding this? My current firmware is 5.00m33-6. I really wanted to play mhp3rd

    • sylv3rblade November 16, 2011 Reply

      Yep, wala naman modification yung Prome. It just adds another layer of compatibility for the PSP. You’ll need Prome-4 for MHP3rd. Download it here.

      • Darkslayer November 19, 2011 Reply

        Thanks po sa reply.. One question lang po. after applying this or prom-4, will it be indicated in the psp that the version changed or basically this is just an add on to play games that requires latest cfw? If nagpalit po ba yung version, how do you get back to 5.00m33-6? Thanks po ulit.

        • sylv3rblade November 20, 2011

          It’s just an add-on, technically same firmware pa rin before you install prometheus. Kung gusto mo magrevert to non-prome, for 5.00 M33, you need a pandora battery to reflash, for 5.50 GEN-D3, just rerun the XGEN Updater.

        • Darkslayer November 20, 2011

          I see..I’m about to install prom-4 add on, pero eto na lang po last concern ko, if I wanted to upgrade to another firmware i.e 5.50 Gen D3 or 6.00 and above firmware while this is in effect, will the process of upgrading be the same? Sorry po kung marami ako question. Thanks po ng marami.

        • sylv3rblade November 20, 2011

          Yep, kung firmware update walang kaso kasi maooverwrite yung prome.

  18. nabako April 19, 2012 Reply

    what if iam on 5.55 version is it ok to use prome
