POPSLoader is a plugin that allows you to play PS1 game on PSP, by improving the startup rate and operational stability of converted PS1 games.

Initially released by Dark_AleX to reproduce PSX games installed in the past FW with another CFW (due to the fact that coverted PS1 games conforms to the PS1 emulator/POPS specifications of the old FW). It was then improved by Virtuous Flame with a new POPS Loader for PRO CFW so that it works with 6.xx PRO.

This plugin is a mod verison of Virtuous Flame's Popsloader v2, introduced by Popsdeco with bugfixes and to supports 6.xx PRO/ME.

Installation

Before installing PopsLoader, you will first need to extract modules from varies FWs. All POPS modules have already been collected in the given link hence you can skip this process.

To install, copy the popsloader folder to the seplugins folder on your Memory Stick.

Modify pops.txt in the same seplugins directory and add the following line to the text file

ms0:/seplugins/popsloader/popsloader.prx 1

For PSP Go, add this line instead

ef0:/seplugins/popsloader/popsloader.prx 1

Note: Please note the folder also comes with a support plugin CDDA Enabler (by Total_Noob) to solve the missing sound/audio issues in playing PS1 games above 4.01 FWs. There are however reports of it causing some PS1 games to freeze, if you choose to use CDDA Enabler along with popsloader, simply add this line to pops.txt (for PSP Go, replace ms0:/ with ef0:/)

ms0:/seplugins/popsloader/cdda_enabler.prx 1

User guide

How to use

By using popsloader, you are able to access the different versions of POPS released, which will greatly increase the compatibility with the games and your chances of being able to make them work at their best.

To use the plugin, start your PSX game while holding R-Trigger until you see the POPS selection screen, and select the POPS version to start the game.

If you select Original from flash at the bottom of the selection screen, it will start the game without using popsloader.

The selected version information is recorded for each game and saved in ms0(ef0):/seplugins/popsloader/pops.cfg.

When you run the game again it will automatically use the same version that you previously selected.
