Requirement: Have a folder named SEPLUGINS in the root of your memory stick.
First of all, what does this do? Why, it pretty much promises you the compatibility of your psx games on psp! Different OFW's work for different games, so this plugin lets you choose which OFW to emulate, therefore solving that dilemma. Without this, you'll have hell getting those games to work. Luckily, this is extremely easy to install!
1. To install, just copy the download's seplugins folder contents into your memory stick's SEPLUGINS folder. Then, you create a text file (via notepad) with this in it:
ms0:/seplugins/popsloader.prx 1
You save that as pops.txt and put it in your psp's /SEPLUGINS folder.
2. Afterwards, open your recovery menu either via VSH or by holding R when turning on your psp. In the recovery menu, look for plugins, click, and enable popsloader by press X. Press O to go back and exit recovery menu.
3. Afterwards, you can choose your psx game on xmb, and hold R before you press X on the game.
