How to put Doom on your PSP
Firstly congrats on downgrading your psp! There has been alot of speculation over when, who and how downgrading PSP's will work.
Question: What firmware version did you downgrade to?
Firmware version 1.0 doesn't need the exploit tools(SeiPsp) to run homebrew so I assume you downgraded to version 1.5.
Anyway...
Instructions for doomPSP on a 1.5-
use SeiPsp utility to place seperate eboot files in the game directory
you should get two folders under this directory.
It should look something like this (depends what you name it):
1. PSP\GAME\DOOMPSP - place all your files here
2. PSP\GAME\DOOMPSP% - contains a small seperated eboot file
Under the folder WITHOUT the percent sign (DOOMPSP) place the WADS folder, SAVE folder and the config file you get with the DoomPsp download.
Then place the doom2.wad(full version Doom 2) file in the wads folder and your ready to rock! :D
NOTE: you can leave the doom.wad(shareware version doom) in the wad folder cause it will automatically run the doom2 wad so you might as well take it out (saves space on your memory stick)
Intsructions on Modded Wad Files:
if you want to use modded wad files you need to name them doom2.wad
Read this thread to get it working:

Also you can only run one wad file (unless you have multiple doom ports on the same memory stick) This is something that will hopefully be fixed in the next version of DoomPsp if there is one!
Hope this gets DoomPsp working for you ;)
