Thanks for the suggestions. There is already a good way to exit a game and jump back in (autoload). Right now if the focus is taken away by a call, the game should pause. If it is not doing that, please let me know.
Not sure you are aware, but there is no need to unzip the games, SmartGear can open zip files directly. When I create the installer, I will add the ability to do file associations, but for me, this doesn't really make sense because I keep all of the games in zip files and associating them would not necessarily be what you want.
I did not put the "LED light" persistent during gameplay because of the poor battery life I am seeing on my MPx200. I have just added this as a checkbox option in the settings page. I will release a new build with it shortly.
All games should work. If something does not work correctly please send me the necessary info to track it down and debug it (e.g. bug encountered, platform, game name).
