Python 3 breaks mra_rom_check.sh

[MAME-GETTER]

You cannot mix tabs and spaces, according the PEP8 styleguide:

Spaces are the preferred indentation method.

Tabs should be used solely to remain consistent with code that is already indented with tabs.

Python 3 disallows mixing the use of tabs and spaces for indentation.

Python 2 code indented with a mixture of tabs and spaces should be converted to using spaces exclusively.

When invoking the Python 2 command line interpreter with the -t option, it issues warnings about code that illegally mixes tabs and spaces. When using -tt these warnings become errors. These options are highly recommended!

All python2 scripts must be updated to python3.
Weird, badly supported language, alas..

It seems it broke the script that turns fast polling on as well

Maybe this is already known but video_settings_optimal.sh is also broken.
*edit - It is just broken. No python.
