Anonymous, there is no 'simple' way to save a game, but if you go into your palm directory on the PC, there is a folder there called Backup. In that folder, there is a file VillageSavegame.PDB.
To keep a backup of a game I do not want to lose, I make a copy of this with a useful name.
When I want to restore a game, I delete the current VillageSavegame.PDB, rename my previously saved file back to VillageSavegame.PDB and then do a hotsync of my palm adding this new file
Hopefully this helps
