Yesterday, everything was working great until I decided to update to 4.2. Now every pal game loads but it is in black and white (usbloader gx). I tried force ntsc but all I get is black screen. I followed this guide http://gbatemp.net/index.php?showtopic=171901 and then I installed cios rev 19 and hermes cios222 ver 4. Any fix to this or can I downgrade back to my old settings?
