There's either
A. Use Gateshark2NTR to make Gateshark codes into NTR codes
B. Use a modified NTR Debugger for Gateshark codes (I forgot where this can be found)
Or if you have a Gateway card, just launch Gateway with their Arm9LoaderHax.bin
Yeah, do that ^^^^^ especially if you enjoy GW cheats. You do realize that if you have PowersavesPro you can use it on your carts and dump the .3DS file then convert it to .CIA?
Well either take the image URL, ending in .jpg or .png or an image file format, and use the "insert image" button and paste the image link there, or just copy and paste the picture into the status field and it will upload as an attachment and show up in your post.
