How do I get Macrofire 2.4.1 to work?

My select button has stopped working (I already opened the front case and pressing it manually, no luck. I think I may have damaged something after putting a full housing case) and I was wondering how to get Macrofire working. I tried understanding the readme but it's not very clear with instructions. So I put everything in the seplugin folder? I ceated those vsh.txt and stuff but still didn't get anything. Am I supposed to run this off XMB or configuration menu? I've never messed around with the seplugin folder or have any idea how it works so I guess that's why I'm stuck.

I'm no n00b to the PSP scene, had an original 1.5 PSP since launch year and had homebrew from the beginning. It's just I didn't use it for a long time and things got very unfamiliar lol. I have a Phat PSP 5.00m33-6 with the 1.50 kernel add-on

EDIT: nvm, figured it out. I just forgot to put "ms0:/seplugins/macrofire.prx" in those vsh, game, and pops text files. The instructions were really bad I guess because of translation and I just checked other seplugin homebrew tutorials to see what happened.
