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.

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.
