So a while back I mentioned to @hunterk in a post that maybe I’ll image my install. Well I have decided to go a few steps furthur than this.
A full install of Linux has many overheads that are not necessary. So, I have started work on an OS that is designed for RetroArch and CRTSwitchRes. This is based on Debian 9 minimal (200mb iso) then just adding only what files are needed.
Here is a short video of it running. Boot ime is between 10 to 20 seconds.
Once this is stable and everything is working I will release this.
