+- 3.04 (tested only region M in emulator so far, but guess all regions EUMACDGJ will work - with English language set in settings) - please ping me and will update this page when confirmed working on hardware.
 - 3.10 (all regions EUMACDGJ - with English language set in settings) - confirmed working on hardware by CTurt, and others. [Only seems to work with English language](https://www.youtube.com/watch?v=zelVQcD7HCY).
 - 3.11 (all regions EUMACDGJ) - confirmed working on hardware by [MrMario2011](https://twitter.com/MrMario2011/status/1277586569738813440), and others. Language setting doesn't seem to matter ([Japanese language works at least](https://twitter.com/kood_infothief/status/1277600247024238592)).

 OK, so turns out porting to different regions/languages is just a matter of finding new jump target, which isn't too difficult.
 
+Prefer using jump targets which aren't part of the language data, so that exploit is compatible with all languages. I might go back and redo 3.10 for this reason.
+
 Porting to different versions, means finding all the function addresses again, which is the time consuming bit.
