I tried and I couldn't get it to work. There is no place to select the total conversion games. I took the same total conversions files (.GRP and .CON) that I had on my Zodiac along with the .duk files (or .duke files, either work) and copied them to my duke3d directory on my N800. On the Palm conversion on my Zodiac if you have these files in the duke3d directory, a menu screen comes up right away when you start Duke3D where you can select the default game or any of the total conversions. Then after making your selection it runs Duke3D to the main menu screen. On my N800, it just goes to the default Duke3D menu screen. I thought maybe there might be a place in New Game to select the total conversions, but there isn't anything there either.
