popsloader to play PS1 Games on PSP

Well, I got a few game files of tombraider and when I tried loading them on my custom PSP firmware 4.05, The games did not show. The reason was they were not normal cso or iso files, but EBOOT.PBP files. But searching on google and various forums, I got this solution which works! But make sure you are on a custome M33 firmware or this won't work.

1. Extract yout EBOOT.PBP file into a folder and copy the folder in the /PSP/GAME folder in your PSP.
2. Download popsloader. Search google for it. there are several versions available, so download what's closer to your firmaware version. Like I first downloaded popsloader for M33 3.71, but it did not work, then I downloaded a popsloader version which worked for all 3.xx firmwars, and it worked for me.
4. When you have the popsloader, you'll see that it has a folder named seplugins. Drag this folder to the root of your PSP. DO NOT PUT THIS FOLDER INSIDE ANY OTHER FOLDER ON YOUR PSP.
5. Now reboot your PSP is recovery mode It's very simple. Just close your PSP and hold the right button while starting the PSP.
6. When inside the recovery mode, choose the plugins option and activate popsloader.prx option using the X button on your PSP.
7. That's it. Now goto your games menu , scroll down to your game and play!
Try different versions of popsloader if it does not work for you!
