I've been considering compressing roms lately as I keep them uncompressed for all systems to prevent SD write cycles from extractions. These wouldn't extract or cache whatsoever, right? Also does RetroArch cache from my current .bin's and .cue's to "/tmp/Retroarch/"? I've been considering changing RetroArch's tmp to "/tmp/" (a RAM drive) but that would choke a pi3 if it tried to cache a PSX game, thus I'm trying to trim them without the need of extraction.

@mitu Good point. I did visit that page, but obviously did not look good enough. :-)
