The project was open source under the GPL. Chowdren also performs additional tasks (such as sprite merging) to ensure the final executable is as small as possible. Fusion’s regular runtime emulates events, hence Chowdren offers an extremely significant increase in performance. The runtime recompiles and optimizes events to C++, allowing it to run on Windows, Linux, Mac OS X, Wii U, 3DS, PS4 and PS Vita, with PS3 and Xbox One being considered.
Chowdren is a C++ runtime for exported Fusion applications and games.
