In a week we are going to release a new wallet.
It will be the pre-release of the final version, that will include e new playable 16bit game and a full emulator.
A new botton will be available in the next version, it will bring you to a complete game database, where you can chose the game and play with in the wallet itself.
A full documentation and an how-to use guide will be put in the wallet directory.
Plus we are working to a mobile version of the wallet, more detail will be announced next week.
Thanks for the update, waiting for it!
