//
// Numerous hacks and 'unsafe' optimizations have been performed on the original 
// Frodo emulator codebase to get it running on the small handheld system. You 
// are strongly encouraged to seek out the official Frodo sources if you're at
// all interested in this emulator code.
//
// The GimliDS emulator is offered as-is, without any warranty. Please see readme.md
