Hi, it's been raining here today (thanks to the tail end of Hurricane Bertha) so I've been having another go at porting.
Here's Open Titus. You need the original full game or shareware data to run. Place game files in /usr/local/home/titus
Source is included in the .opk.
I've tested the first level but unfortunately cannot progress as I suck at platformers :'(
Enjoy
