You may be thinking "why do I need to use a controller on my portable game system? that doesn't make sense!" well there are a few ways you can use it for! If your at your desk you can just prob your PSP Go against something and play with the PS3 controller if you don't want to be picking it up and putting it down, or if you have your PSP connected to your TV, you have the freedom of being farther away. Or you could let your friend play and freak him out by hitting random buttons on the controller! Any way it is a very simple process and costs nothing!
This will ONLY work on the PSP Go because it has Bluetooth, unlike the other PSP Models.
Step 1: Get Your Matterials
-PSP Go charging cable
-PS3 (temporarily, I'll explain later)
-PS3 Controller (Sixaxis or Dualshock, I recommend Sixaxis because it's lighter, and you can't you rumble anyway on the PSP [YET])
Step 2: Prep the PSP
Step 3: Prep the Controller
Step 4: Press the PS Button
Step 5: Tips
-Even when the PSP is closed, you can still play, and it won't go into the closed state (clock, calendar, etc)
-You can only have one controller synced at a time
-The Controller usually syncs with the PSP in about 5 seconds after just turning it on
-The L1 and L2/R1 and R2 both function as L/R respectively
-There is absolutely no lag, although this seems given, I just was surprised by it
-Be creative and leave comments on how you use this!
