DSL from cd start very fast

just cut all gnome/kde and other useless stuff, just pure game and essential system elements [kernel, libraries and little configuration]

after boot, all game fles are on ram

booted game have access to hdd specified folder after you enter password for user. so you can save game.

gamecd containt kernel that we need, drivers, good set of libraries.

so it can be started from cd, or from linux you boot everyday[if libraries compatible]
