I was a child of the 60s so most of the games I play are Mame type. I seem ti be addicted to obtaining more and more roms. Quite honestly I only play a few games regularly

Mr.Do, Wardner, New Zealand Story, Crash fighter, Crystal Castles yet I somehow have amassed 500GB of roms and stuff.

Is there a document that explains the layout of the roms directories

A typical set has something like this

BIOS
icons
LaunchingScreens
retropiemenu
scripts
splashscreens
videoloadingscreens

Everything except roms is about 3GB

roms is say 400GB

I’ve worked out that the mame stuff is in arcade

How can I produce a cutdown version with all the mame stuff but a selection from all the other stuff to show people.

IS there a script to say produce a 64GB version of roms?
