Installing Homebrew applications is actually a whole lot easier then it sounds. For the most part, it's all just "Drag & Drop." Although some emulators may require you to rename ROMs, or place them in specific folders.

Please note that while this covers quite a few applications out there, it doesn't cover every single one! Whenever possible, please read the documentation that comes with the Homebrew application you download. Although, most homebrew applications don't include documention, so that's where this guide comes in handy

Creating the GAME folder on your PSP...if it's not there all-ready.
The GAME folder on the PSP, is where ALL homemade applications go. Even if it's a game or not.

Just follow the pictures, and the captions!

Click on the PSP Folder as shown below.

This is the PSP Folder on your memory card. It probably doesn't look like this though. Ignore the JAVA Folder. Notice the GAME folder? If that folder isn't there already, make a new folder, and name it GAME.

As you can see, there are a few games installed in the GAME folder already. To install games on the PSP, it's quite easy. Just create a folder within the GAME folder for the name of the application...and then...

Unzip the contents of the application into the folder you just created, just like is shown here with SNES9X.

This is how ALL applications are installed. It's just a few simple steps. Here's a review:
-Open up your PSP folder.
-Goto the folder called GAME.
-Create a folder for the application you'll be installing. You can name the folder anything you want. I.E. I could name the SNES folder SuperNES, or SnEs. It doesn't matter.
-Unzip, or copy from your hard-drive, all the files of the application to your newly made folder.
Ta-da, done!
To run the applications on your PSP, just simply goto:
-Game
-Memory Stick
-Choose the program you want to run!

Emulator Basics
Now, as I'm sure you all know, games with Emulators are called ROMs.
Now, with some emulators, ROMs must be placed in specific directorys, while with other emulators, they can be placed almost virtually anywhere.
When in doubt about your emulator, ether goto the home-page of the emulator, experement, or read the directions.


Here's a low-down on some emulators though, and where to place the ROMs, as well as other information. Keep in mind, this information will most likely become invalid sooner or later. Please PLEASE check the program creators home-page, or documentation that comes with the software.

SNES9X
You can place the ROM anywhere in the directory that you installed SNES9X in. It can only run roms that have the SMC extension.
Example: Chronotrigger.SMC.

InfoNES
Easy enough....just put the NES roms in the same folder where you installed InfoNES.

Sega Master System (SMS), also plays GameGear games, too.
Another easy to figure out one. Just place all roms in the ROM directory that you'll find when you un-zip the program. Not a tough one to figure out. Razz

Gameboy/Gameboy Color (RIN v1.13)
If you've read the ReadMe, then you'll know that you can place the ROM's anywhere in the directory you installed it. ^^

So... as you can see, installing, and getting the emulators to run ROMs isn't exactly tough work. If you have an emulator that isn't listed, then experiment
