Emulators organiser is completely free. You don't need to donate money to unlock stuff or features. It's completely free.
Optional donation would be very welcomed and valuable support for continuing the Emulator Organizer and another AHD projects.
Recently, I moved to Germany as a refugee and live now with the support of the refugees program.. I left my laptop (witch I use to program) in syria and I cannot buy a new one and continue the work on all the programs until I get a job, witch may take a while (a long one till I learn German). The money donated will help me buy a pc/laptop to continue the development of the programs.
Thanks for your generosity.
