Here are some programs I've written through the years. You may find some fun, some interesting, and some useful.

 

 

  Overall, I think the program for the Gameboy Advance that converts a MIDI to an S3M or MOD is the neatest. It has a windows interface, and would be really great for developers using "Ham". Another program which may be of interest is "Course Organizer". It was a program I wrote while learning "C" and has source code included. It has a mouse interface and boxes that click and float like in "Excel". Another program which you may find neat is the Golfball Shadow Demo. I wrote this after I wrote "Sharpshooter's Miniature Golf" and it uses pure DirectX whereas Sharpshooters uses OpenGL for graphics. I hope programmers and novices find these examples useful. 2 full-blown windows games I programmed more than 10 years ago can be found HERE.
