Doh... I renamed the game file extension from .bas to .ba, loaded it into Virtual-T... and it appears to run without errors!
Which is great, but leaves me without a project. Not really; I need to reformat it for the 40 column screen, add in an option to exit mid-game, things like that. Oh... the game's name? The Oregon Trail. My plan now, after fitting it to the 40 column screen (any way I could get it to work with View80?), is to "morph" it into "The Organ Trail", a modern version set in a post-apocalyptic world. Maybe even add some ascii graphics.
