Good to hear 1,4 is having the same positive effect on your cube as on mine, I have two cubes one drive 6 which would play nearly every copy thrown at it and a new Black cube drive 8 which although seemed to run copies okay would DRE after about 2 Mins. Whith GCOS 1.4 tested Mario Power Tennis for over 1 hour and no DRE also all of my NTSC and PAL copies seem to be running fine.
