came across this here: How to Burn Retro Game Images With All Free Software.
The purpose of this tutorial is to show you how to burn game images to CD/DVD. This tutorial will break it down to image format rather than console specific. Why? Because burning a BIN/CUE (for example) is exactly the same whether it be for a Saturn, Sega CD, or NeoGeo CD game.
Not had time for a proper check but I may have a look and see what can be turned into Linux instructions.
