Yes and no. Some games can be converted to some other games.
what little has been proven possible is completely undocumented, and there are a number of theoretically possible conversions that will require some reverse engineering work to make possible... but no one has done this yet (or if they haven't they haven't told anyone).
Rezon converted from another board fits squarely in the "theoretically possible but a lot of reverse engineering work to be done"
