Patrick Davidson's TI-85 page

Here you can get a few of my TI-85 games. All of the recent programs require a TI-85 with Usgard version 1.5. There are also some older games for ZShell (which can also run under Usgard). The download archives include the Usgard string files, source code, and documentation. The Orzunoid page also has level files and level editors.

Usgard games available for download

Additionally, my ZShell page has some of my older TI-85 games, which run under ZShell (and any compatible OS, such as Usgard). Many of these are simply older versions of the games above.
