Ok, what you have to do is simple. If you're using the download from the stickied topic, go into the psplegacy_r4 folder, and there's two folders, legacy and src. Extract legacy, and put the IWADs you want it to play in the same directory as the eboot folder. For example, I have Doom, Doom 2, Plutonia, and TNT. I can't say where I got mine, as they're still being sold by the game developers, so if you want to get your wads the legit way, you're going to have to fork over some cash.
Anyways, once you're done, put the legacy folder into a Store-Compressed zip file (0 Compression) called install.zip, and put it in a PSP save file of your choice (remember the folder name of the save file, as you'll have to hunt for it in vHBL), then transfer it to the Vita and install it.
