Place payload.dat on the SD root, and ugopwn in the private\ds\app\4B475545 folder, along with a .nds on the root called "boot.nds"

Then, open flipnote, and open the ugopwn folder

Select the flipnote with one frame(should be Flipnote 1) and copy the frame

Then, open Flipnote 2, open the frame menu, and press right until a new frame is made

Now comes the fun part: Click the paste button 122 times, or at least as close to that as you can be

Then hit erase, and it should bring you to frame 2.

Click paste, then stage 1 will load stage 2, to then load your .nds

Congrats! You should be running the .nds now!
