Patrick Davidson's TI-89 Page

Here you can obtain my TI-89 games. These games also work on the TI-89 Titanium as well. They are all written in assembly or C to take full advantage of the capabilites of the calculator. All of these are "nostub" games so no "shell" or "kernel" is required (though they will still work if one is installed). They are compatible with hardware version 1 and 2, and all AMS versions from 1.00 to 2.09 at least (and version 3.00 or higher if you have the TI-89 Titanium).
