[ssokolow]

I'm also getting AttributeError: 'bytes' object has no attribute 'encode' on the console with both 0.2.3 and commit 010b279 on Lubuntu 14.04.

Given that error, I suspect the issue is that the code was written for Python 2 but *buntu 14.04 only has PyQt5 packages for Python 3 so I'm having to run it as python3 m64py rather than ./m64py.

[promi]

The problem is caused by this line:

mupen64plus-ui-python/src/m64py/frontend/input.py

Line 244 in 6179216

self.config.set_parameter("name", devicename.encode())

"devicename" is of type "bytes" which has no "encode" method.

Commenting out lines 243-244 makes the problem disappear which I'm using as a workaround for now.

[promi]

I turns out the workaround is no good, now the config dialog is saving "key(...)" instead of "button(...)" or "axis(...)". The better workaround is to set the input config by hand and don't touch the input config dialog for now.

This issue should be fixed with #73
