I spent much of today porting my 2006 game "Castle Adventure" from TI-83 Basic to Inform 6. Here is the result.
Link to the I6 source code:
Bug reports gladly accepted, although terseness and lack of character motivation aren't going to be considered bugs.
The point of the original was to fit a passable text adventure into about 7K of RAM and a 96x64-pixel screen; the point of today's Inform port is to reproduce the original's behavior as exactly as possible.
The TI-83 game had a sort of "autocomplete" feature on the parser, so you could just type "W" and it would expand to "WEST", then hit up-arrow and it would change to "WEAR" (but only if you were carrying something wearable). If the letter you typed wasn't valid in the given context, nothing would appear on the screen. Certain verbs, like "PUSH", would appear only in certain locations, and certain nouns would only appear when given a specific verb (for example, I didn't need to worry about the response to "PUSH OIL" because that input was literally impossible). Inform doesn't have a good way of simulating these features, but I don't think I really need to provide a spoiler list of verbs, and I think I managed to cover all of the wacky input possibilities with messages like "Don't be silly!" If I missed some, feel free to let me know.
