Implementations

FunkyBoy is developed with keeping portability in mind. The core is developed as an isolated module which can be easily integrated in a platform specific implementation.

The implementations of FunkyBoy are classified as primary or secondary implementations. The main focus lies on the primary implementations to get them working properly. Secondary implementations provide basic functionality, but may experience slow emulation. Those performance issues will be tackled at a later stage of development.
