After the release of PSP Firmware v3.30 , Dark_Alex began a range of news regarding his will to release a OE version of the firmware due to it’s PS1 capabilities. Well he sure delivered on that, and today has release v3.30 OE-A. Thank you Dark_Alex we appreciate your hard work!

3.30 OE-A changes:

• Updated from psp firmware 3.10 to 3.30
• Fixed a bug that could have caused instability in 3.10 OE after recovering from sleep mode.
• Patched a protection that prevents the firmware to load higher firmware modules.

Installation instructions:

- Copy oeupdmaker and oeupdmaker% to /PSP/GAME if you are in 1.50, or to /PSP/GAME150 if you are in any SE/OE version. Get the 1.50 and 3.30 Sony updaters (of any region, because all are currently the same), and copy them in the oeupdmaker directory with the names 150.PBP and 330.PBP.

Execute the program, and it will generate the DATA.DXAR file. Although the program will check its integrity at the end, you can also check it with the following checksums:

CRC32: A0723B56
MD5: DEBFC0488D088C384021231814514DA9
SHA1: 7AB9A6928BD08E26F9BEB18C3A2314AD0C745964

- Copy 330oeflasher and 330oeflasher% to /PSP/GAME if you are in 1.50, or to /PSP/GAME150 if you are in any SE/OE version. Move the DATA.DXAR to 330oeflasher directory.

You need 75% battery, although you can skip this if you pressed L+triangle while loading the program.

About the PSP Emulator:

popsloader note: it won’t work on 3.30 OE due to sony rearranging again the module list of pspbtcnf_pops. (thanks sony for destroying my backwards compatibility again). I’ll make a new version one of these days to support all current pops in 3.30 OE, 3.10 OE and maybe 3.03 OE-C.
