Some info in case someone wants to run this demo on linux. Normally you can run rpgmaker games fine on linux with nw.js, but this one fails because the casing of the filenames in the game doesn’t match the filesystem.
Get ciopfs from your distro or from here. Also get nw.js (normal, you don’t need the full sdk). Then open a shell:
cd where/you/want/the/game
mkdir data insensitive
ciopfs data insensitive
cd insensitive
unzip /path/to/MobbPrimePublic.zip
path/to/nwjs/nw .
and hopefully your game will start.
You’ll need to rerun the ciopfs command after a reboot.
