7.0-pc, from here on itch. I believe it was the Mediafire download, can't quite remember. I haven't tried multiple downloads of that version.
JoiPlay is updated with the latest free release from Nov. 2024, which should be able to handle Ren'Py 8.3.3.
I tried looking at the code, but all I could figure out is that I don't understand Renpy folders (00iconbutton.rpy isn't even in the /game folder like the error says, but /renpy/common), and that python syntax is too different from C++/Java for me to even guess what could be wrong with line 42.
I've reluctantly switched to the Android version for now. It works, it's fun, but well... you know how you fit it into 1.4GB. Either way, don't worry too much.
