OK flyers. This GPS works by doing something similar to what was gleaned from the PocketFMS site.
First insert your formatted blank data card in the GPS. Connect your PC to the GPS using the data cable & Activesync and use the 'Install Skydemon Inflight' utility on the Programs menu. Once this utility finishes you will find that if you ticked the box 'start Skydemon after installation' (or words to that effect), Skydemon Inflight will start on your GPS.However, on subsequent re-boots of the GPS you will find that the prgramme won't run. The GPS boots to a menu which lets you choose various options - navigation/video/mp3/game etc. The game is rubbish, so the trick is to change the right file so that when you click on 'game', instead you get Skydemon.
Using Activesync you need to locate the file Residentflash\Dshell\mshell.ini then transfer a copy to your PC. (You can't edit it while its still on the GPS)
Change the 'game' part of the file to read:
Game = \SDMMC\SkyDemon\SkyDemon.exe
Then transfer the file back to the original location on the GPS.
Then the GPS needs to be fully rebooted. i.e. Use the switch at the back, not the button at the top. This is what gave me trouble, if you just use the button on top, the new file will not be loaded & SkyDemon won't run. Subsequent boots can be from either switch.
Happy flying!
