I don't think AGI/SCI0-1 games are viable to be played on the 2x, or at least, not without a mini keyboard. Can you imagine trying to type commands on a virtual keyboard? *shudders* Sadly however, the only interpreters available do just that - none of the later stuff.
Allan.
How about a modified interpreter that displayed nouns that were close enough to the character to interact with on along the bottom of the screen, displayed inventory nouns on presing left click, and displayed verbs the engine would understand in context of them on pressing another button. Then simply select the noun/verb combination that makes sense. It could, conceivably, be faster than a virtual keyboard - indeed, I don;t see why it couldn't (though I doubt it would) be possible to make an early SCI0-1/AGI game behave fairly similarly to SCUMM games.
Somehow doubt anyone would ever consider implementing something like that, though
