29/01 - Added basic driver for Xain´d Sleena with sound. Sprites, backgrounds and colors are missing

28/01 - These days I´m having some troubles with the IO´s of Galaga (reaches the main screen, but goes crazy with coin insertion), so I shall change the driver to see if I clear my mind a little, and then return to it. I´ll start with the driver of Suna 8 bits (Hard Head and Hard Head 2) and the Xain´d Sleena driver. And between all this I will review the drivers posted by Francenm some months ago, Sauro, System1 and Warp-Warp.
