FOR DISCO INFERNO -
OK go here for the version of DOOM I use -
This is D-Pad DOOM for if you prefer to play on the D-Pad. I do but both versions work just fine -

This is the regular version.

Also make sure you are using the latest SEI -

Then unzip all the DOOM files into a folder called "DOOM-PSP", the Zip file should do this for you. The folder will have the EBOOT in it along with a WADS and a SAVE folder.
Now open SEI and tell it the program is "DOOM-PSP" and then selct WHOLE FOLDER and select the folder called "DOOM-PSP" that you unzipped the zip file to.
Make sure you have HIDE CORRUPT DATA unselected and hit GENERATE. Once it's done go and test it.
Hopefully if all went right it should have worked, now you can use the LIST MANAGER tool in SEI to move the corrupt data to the bottom of your list.
Let me know if this works for you.
