Think keen 4 is also shareware unless chocolate keen doesn't support it

Yeah no keen4 support

Yeah. Keens 1 through 3 were the Vorticon engine while 4 through 6 were the Galaxy engine. Commander Genius is really neat for having support for bloody everything, but I really like the idea of including a couple more source ports for Keen.

I just realized while testing on ROCKNIX that this source port expects all gamedata files to be uppercase and ROCKNIX made this apparent when I tried Episodes 2 and 3 which my files were all lowercase. I've adjusted the shell scripts for these episodes to check for lowercase files and make them uppercase if so and it worked like a charm. Here's the updated zip that addresses this.
