Games Base Directory
The base game directory is where all of the games are stored. Inside, the folder structure will look something like this
Base > 000 > ... 001 > ...
The numbered folders are game pages that /bin/chmenu will switch to, 000 is the default game folder.
You can also separate games by system or even system and region for use with multi-booting by placing the pages in a folder one of these names:
Base > snes-eur > 000 > ... 001 > ...
