I've looked at Shindou Mario a few times, but it has a lot of compression. My hope has been that someone from the Mario hacking groups who has experience with the ins/outs of Mario 64 would take on this project. No luck yet.
Similarly, since I have experience with the Zelda games, I've looked into translating the original Japanese releases of Majora's Mask to English so people here could experience the "hard mode" of not having the owl statues for saving. I got pretty far where all the text is imported, but I need to make some major re-writes to the text functions so it displays the longest sections of text properly. Currently it just displays a blank screen for those lines instead.
