I'll help deal with any issues that may occur. Just post them here.
There is no MacOS version. I’m assuming you’re using Wine or something. I actually had forgotten to add a note in game about this, but the “select key” is X. It also says so on the game’s page.
EDIT: Just saw your edit. xD
Try unplugging it (leave it unplugged) and open the controller config again. If it says "controller not detected" or something along those lines, then it's a compatibility error. Otherwise, it means you have something else the game is mistaking for a controller connected. Unfortunately I don't have that controller, so I can't fix it if it's a compatibility error.
I was planning on a Mac version, but either the packaging tool or the OS is making it impossible. :(
it sounds like you're running the wrong file or something.
Hmm - not sure. at the top of the code (like line 3/4) there is an "import data.text as data" line. Seems like that is what the error is pointing to. I don't see a file by that name anywhere...is that generated by a make file or something?
