As far as I know they didn't, and you don't really need the magicdata to change track order with gpx_patch, just edit the track set file. I can't remember who discovered the magicdata but I doubt it was the gc team. It sure changed things when we got it. Most of the updated tracks either have it already installed or the data file is included so you can either install it or not. I found the magicdata handy for fiddling with the grip and cc cars although sometimes the lap times can become unrealistic and it defeats the purpose. Good fun though
