Dark_AleX has pleased the masses once more, this time, with the sequel to his 3.02 custom firmware, 3.03 OE-A!

Here is the changelog:

• Change from firmware 3.02 to 3.03
• Added support for compression in psx isos (look at popstation documentation for more details).
• Added support for decrypted document.dat (psx games manual) (look at docmaker documentation for more details).
• Fixed a bug regarding free region: a stupid bug caused it not to work at all.
  Now it should work, although it has not been tested due to lack of umd's of different regions
  between the testers and me.
• Some generic bug fixes in the code.
• Redded the sdk.

Wow, what a release! And to think, so many people thought it was a hoax, simply because they thought 3.03 was a security release!

To install, follow these instructions:
1. Copy oeupdatemaker and oeupdatemaker% to /PSP/GAME if you are in firmware 1.50, or to /PSP/GAME150 if you are in 2.71 SE or 3.02 OE.

2. Get the 1.50 and 3.03 sony updates, and put them in the oeupdatemaker folder with the names 150.PBP and 303.PBP (respectively).

3. The program will generate a DATA.DXAR file, so please check the hashes to see that they match the following:
MD5: 03186D46D2F1B0ACD923098BEBC87281
SHA1: 3C80833A970EEA16A94D74DAFF6220889A9CEE4A

4. Copy 303oeflasher and 303oeflasher% to /PSP/GAME if you are in 1.50, or to /PSP/GAME150 if you are in 2.71 SE or 3.02 OE. Move the DATA.DXAR file to the 303oeflasher.

5. Run the program from the XMB. When it finishes, it will ask you to reboot the PSP; when you do that, you will be in 3.03 OE-A!

I've tested this, and I can honestly say that it is fantastic!
