If u reply plz can u be specific and give me links tooo as this would really help!
Thanks a bunch!!!! WEDGIE208

Tried reading the instructions?

A couple of things here..

If you actually did read over a thousand websites and follow all the instructions, you would know (and I'm making an assumption here, since you can't even provide viable info) that you're using an OFFICIAL firmware. That means no homebrew. Also, openly admitting that you're pirating isn't looked highly upon here either.. food for thought.

You mention wanting to play a DS game, yet a simple two second google search for "DS PSP emulator" will tell you that DS emulation on a psp isn't gonna happen anytime soon. Take Wally's advice and continue reading. If you ARE using official firmware, and your motherboard is supported (not a TA-082 model) grab a pandora battery and make a magic memory stick. People's signatures on here have links on how to do that... look around.

hey thanks 4 replying and soz 4 l8 reply as i had no internet 4 2 weeks.... so do i need this "pandora battery" 4 this to work??

also i'm a bit of a dumbass and would REALLY appriciate it if someone could give me some specific instructions with the nessesary hyper links and downloads on to get 1 GBA game on ma PSP..... THANKS again!!!
