1. Where is the source code?
Any user who has obtained a copy of Magic DOSBox can email us and we’ll provide the source code — usually on the next business day. Please add your trackable order number to the email for the donated version.
2. Why there are two versions?
Magic DOSBox has two versions: free and donated. They are 90% identical and we hope that people who like the free version will support further development by purchasing the donated version. The additional 10% of functionality will be their reward.  Money collected from purchases are used to buy testing devices and running this server.
3. How can I support further development?

You can buy us a beer or book! Or,  you can buy the donated version of Magic DOSBox. Another way to support us is to help with producing foreground and background images for widgets, or with translating parts of the app or website.
