zetastrike Posted April 24, 2016 Share Posted April 24, 2016 I just started fiddling with my SIO2PC unit and noticed when I first power on my 800XL with the cable connected, the screen is covered with random messy yellow graphics which remain there until I hit the reset button, then it goes to the regular startup screen and loads whatever disk image I've mounted. From that moment on, everything is normal. I haven't found any explanation from searching. This doesn't happen when I play a cartridge game.
