Okay, joiplay doesn't seem to work because of the file size (over 7mb for common events and 400mb in total of parallaxes is crazy). There is, however, an apk on Platinmods, which seems to work. It still takes 15-30 seconds to load, but it's usable. The bugs are still there though, so you'll need to get Mt manager to edit and create a new apk with the bugs removed before playing (I learned this too late and can't advance due to the water flute, and you can't edit the apk and keep the save file, so you need to create a new apk before you even start playing).
