The modshop told me I don't need any update btw. I got the newest version of xKey. xKey supports NTFS, FAT32, etc... but xBox itself supports only FAT32. That might explain something. K. Imma write down from my brain what I got so far for myself: #1 Download games to your 2TB NTFS HDD. #2 Name the folder on the HDD "games". #3 All games come in there. They MUST be .ISO files. #4 The HDD must be already running before turning on the xBox. #5 Put the USB-Dongle in the nearest outcome of the white cable in that exact USB slot. #6 Connect the HDD with the USB-Dongle. #7 Turn on the xBox in the xKey mode by either pressing the xBox controller menu button or by pressing the power button on the xBox itself. #8 Wait until it's turned on properly. #9 Either:A) Open the xBox by pressing "A" on the controller or B) Pushing the "open tray" button on the xBox. #10 Repeat #9, so the tray closes digitally and / or physically. #11 ??? A "mixed media" disc MUST show up. That is the indicator that it's working ??? <--- Not 100% sure about this. #12 Go to "apps" and select the picture app. The HDD should be shown as a media disc. Browse through and select an ISO in the "games" folder. By doing so you switch the game. #13 You're able to play now.
