I've been working on a little homebrew game for the 3DS, mainly to help myself practice TGM. Since I got GM, it seems to be doing its job, so I'm going to start releasing it to the public. It's not very full-featured, but it does the job if you just want to play TGM on the go (and it even has Death in time for the carnival!). Here's the link: https://github.com/Fusxfaranto/gm3ds/releases/ Enjoy! If you have any issues using it, or if there are any accuracy issues you notice, please post here (or contact me on IRC) to let me know.
Awesome, a reason to get homebrew up and running on my old 3DS! My only feature request: an additional counterclockwise rotation on the Y button.
