Place the folder OEB_UPDATE inside /PSP/GAME150 and run it.
The update will take a very little time, since it only updates the files needed.
The new addition of this update is the ability of playing your own psx games, using the provided
tool (popstation) to convert them.
Although, a feature that was in OE-A and i forgot to comment:
You can use plugins in psx games. Just create a file called pops.txt inside seplugins, with the path of your modules."
I guess this is the perfect Christmas gift for all hacker wannabes, and most of all, this allows you to play PS1 games on the PSP without having to download them from the PlayStation network. Besides, you don't have to use the PS3 to transfer them onto your handheld.
Some of you may wonder about the legality of this firmware altering, but I'm almost certain that it steps into the boundaries of the law, as long as the PS1 isos are ripped from games already owned. If I'm wrong, please let me know.
