I'm building an arcade machine that will come equipped with its own "operating system". The OS will be a skinned version of Retroarch. I understand that much of the work will be done with XML files. However, there will also be to have the app boot-loaded (as opposed to loading into Mac or Windows). This is a long-term project. And the goal would be to expand the OS as time goes on with more features.
