Games that doesn't run are :
*'''commando.dsk''': pixels that should be deleted are not deleted (only VRAM &C000-FFFF seems used)
*'''atomdriv.dsk''' : freeze (the music does freeze also).*'''split ink demo.dsk''' : (from cpcrulez) : may help about ink raster calibration.*'''superski''' : strange no up/down joystick on first menu, no up/down joystick during big jump.In slalom you can't stop. This game did run correctly before interrupt r52 counter reset implementation.*'''buggyboy''': I found one dsk running correctly and another not : problem on this last one is about turning left/right effect : the car continues straight.
crazycar.dsk does use lowerVRAM=00 (&0000-3FFF and &C000-FFFF area for VRAM)
