If I were a really good programmer and artist, and wanted to spend ages ripping out my own hair and tightening up the graphics on Level 3, I would dedicate some time to giving SWAT Kats the video game it deserved. Then, I'd get sued to oblivion. What I'd probably have to do is program and distribute a generic title, then offer a free "skin" that converts it into the SWAT Kats-themed game that was intended all along.
