I have both BF3 discs on my JTAG's HDD (Singleplayer and Multiplayer). When I select "Campaign" on my singleplayer disc, it tells me to insert the singleplayer disc, even though it's the one currently being played. I'm just booting the games up from the extracted ISOs in my content folder. I'm assuming that ISO2GOD may help solve this problem, but it won't open XDG3 ISO files (which is just a .rar with a .iso extension, containing $System Update, AUDIO_TS, and VIDEO_TS. Does anybody know how I can fix this? I'm stumped...
