WARNING: Still under construction\n\n\
Created in such a way so it should not conflict with other supermodel installs\n\n\
ROM Extensions: .zip\n\n\
Copy your games to $romdir/supermodel\n\n\
Supermodel emulator directories and files are added in:\n\
~/RetroPie/roms/supermodel/model3emu/mechafatnick\n\
(NVRAM, Saves, Supermodel.ini and Supermodel.log)\n\n\
If needed then add these lines to your Supermodel.ini,\n\
and alter them to your needs under [GLOBAL]:\n\
XResolution=800 ; Default value 496\n\
YResolution=600 ; Default value 384\n\
FullScreen=1; Default value 0\n\
WideScreen=0\n\
Stretch=1; Default value 0\n\
WideBackground=0\n\
\n\n\
Select a good equivalent resolution video mode in the RetroPie boot menu to get a proper fullscreen.\
If you use the regular runcommand then the resolution of the Supermodel.ini file is used.\
Otherwise the resolution is used of the runcommands with the adding the resolution.\
If you know your resolution and you have added it to your ini file,\
or you have selected the runcommand with the proper resolution,\
then changing the video mode should not be nessecary.\
