Thanks!!!!!!!!!!! The hex edit works on EDGE firmware v1.5! You can finally click the 3C button without it freezing!
Here is how to Hex Edit the rom:
Download the free trial of
Hexworkshop
Install it, it will tell you to restart your computer but just click No, the program will work without restarting
Click File -> Open -> xpa-copc-cracked.nds (make sure it is pre-patched)
When loaded you will see lots of digits and numbers
At the top toolbar, by the search box, click the image to the very left of it, has an arrow next to a little picture of a piece of paper
When opened, in the offset box, type 0x278A3 and be sure to click the "hex" option underneath, and click to the right, "current position", and click "Go"
In the window it will go right to the offset, you will then see the 0A in the first box, click infront of the 0 and just type E in CAPS...done
Then do the same thing for offset 0x3FA6B
When finished, click File -> Save As... -> and overwrite the patched rom.
Congrats! You can now play it and click the 3C button! And also the "X" button on the bottom screen!
