PRO-C/C2 Plugin doesn't show up about procfw HOT 3 OPEN

Most probably you didn't name the .txt files properly.
The text files containing full pathnames for plugins are as follows:
game.txt - plugins enabled in games
vsh.txt - plugins enabled in the XMB
pops.txt - plugins enabled in the PSOne Emulator.

make sure the paths are properly typed in those text files as well.

Also make sure you have the seplugins folder on the root of your MS. not in 
MP_ROOT folder.
Check if your Plugins support is enabled in recovery menu>advanced.

I apologize if i was unclear about this, but I had already assumed one or the 
other of those was the problem when I'd begun, and already tried bith of the 
issues. Original folder creation fo SEPLUGINS folder was in the MS root folder 
just like the ISO folder is. And i have tried every variation of these .txt 
file names and put the filepath names just as shown by the verified working 
guides. Ergo, my posting here. I dont mean this to sound rude or disrespectful, 
I had just assumed that my initial post covered these types of simple mistakes 
as things ive already checked before showing up here. And as for checking in 
the ecovery menu, i had made sure it was turned on before i began attempting to 
work these plugins into the program.
