Here is a step by step guide for installing 3.40 OE-A. Please note that you must be running 1.50, or any of the OE series firmware to begin this installation.

First grab the 3.40 OE-A files.

1. Copy oeupdmaker and oeupdmaker% to X:/PSP/GAME if you are in 1.50, or to X:/PSP/GAME150 if you are running OE.

2. Now download the 1.50 and 3.40 updates which you can grab below:
1.50 Update
3.40 Update

3. Place these 2 updates in the oeupdmaker folder and ensure they are named exactly like this 150.PBP and 340.PBP. Now navigate to the game menu on your PSP and execute the update maker. It will take a few minutes to create the file, once finished a DATA.DXAR will be found in the oeupdmaker folder.

Please note: If you get an error message that says "Invalid SHA-1" when creating the DXAR do not proceed further. This means you have a faulty memory stick and a corrupt DATA.DXAR was created. Start over using a different memory stick.

4. Copy 340oeflasher and 340oeflasher% to X:/PSP/GAME if you are in 1.50, or to X:/PSP/GAME150 if you are running OE.

5. Copy the DATA.DXAR created in step 3 to the 340oeflasher folder.

6. Navigate to the game menu on your PSP, run the 3.40 OE-A flasher and follow the on screen instructions. Once done your PSP will now be running 3.40 OE-A

these instructions are awesome!
i can now play Vagrant Story on my PSP. probably the best game i've played onthe damn thing. i don't understand why Sony hasn't done this yet, if they were smart they'd take all the PSX games and put them on compilation UMD's. but unfortunately that probably won't happen.

Thank you

Its the folder path, if you don't have it just make a GAME150 folder.
