/* Tests done */
'''crazycar.dsk''' does use lowerVRAM=00 (&0000-3FFF and &C000-FFFF area for VRAM)
'''crazycar2.dsk''' does use lowerVRAM=10 (&8000-BFFF and &C000-FFFF area for VRAM) while overscan presentation, and lowerVRAM=00 (&0000-3FFF and &C000-FFFF area for VRAM) during play.Run fine since r005.7
'''buggyboy.dsk''': I found one dsk running correctly and another not : problem on this last one is about turning left/right effect : the car continues straight (it seems a prototype bad version)
