That's cool. I wonder if the format is ISO or a folder. Almost every site that hosts Xbox anymore just hosts zipped folder format for use with people who have modded their Xboxes to play from hard drives. I typically am not a fan of the FTP method of transferring games. I wish there was an easier plug and play copying solution.
If the emulator for PC is finally becoming usable for retail games, then that is a great and necessary step. That Xbox hardware is almost like a PC on its own and won't run forever.
