How do I start making a translation hack for 3DS? I'd like to translate Club Nintendo Picross Plus to English. I'm an experienced reverse engineer, so things like disassembling the game executable and ARM assembly language aren't a problem for me. I also know how to decrypt the game executable and unpack the romfs. What I don't know how to do is actually apply my patches to the game executable and romfs to run them on my 3DS. My 3DS is A9LH'd.
