1. What firmware do you have.
2. If you have 1.5 then:
There should be 2 eboot folders. One with a %behind the name and one without a % behind the name. Copy those both.
Go into the root of your PSP memory stick by hooking up your USB cable from your PSP and your computer and going into settings and clicking USB connection.
Now that you are in the root of your mem stick create a PSP folder with capitals in it, and then inside the PSP folder create a GAME folder. Inside the GAME folder with capitals, paste those two folders that you copied earlier (your emulator)
You are done! Well, thats if you have a 1.5.
3. If you have a 2.0 then you have to install an eboot loader. Go onto the Tutorials section located here to see how to install homebrew on a 2.0+ firmware:
