So I got Pokemon XD as a .gcm file and I read online that you just have to change .gcm to .iso and you'll be fine. Well I did that but when I insert the CD and load up the backup launcher it shows the screen then shows the boot menu. Now I tryed all the possiblities. NTSC, PAL50, PAL60, HDTV, etc. All of them have the same effect. A black screen and nothing, not even sound. So can someone tell me the problem? and solution.
