I already own Village Sim, Plant and Fish Tycoon. If I were to buy a new handhled would I be able to get new codes for the previous purchased games or would they work if the HotSync ID was the same?

If you plan on ditching your old handheld and syncing all of your previous data to your new handheld, you won't have any problems. Use the same Hotsync ID and your old data (including programs) will appear on your new unit.

If you plan on using both your old handheld and a new one also, then you will have to have different ID's if you plan on syncing from the same computer.

As long as the HotSync ID and platform (Palm, PPC) are the same your codes will work. If you switch platforms from Palm to PPC (or vice versa), you can fill out the support form and LDW will help you with new codes.

I am planning on getting a Life Drive Mobile Manager, so I shouldn't have a problem, right?

You shouldn't have any problems with your registration codes when switching to a LifeDrive, as long as you keep your HotSync ID the same.
