Y'know what? I think the one thing better than a VGA SCI01 template to make parser-based VGA games in is one that's based on SCI11, considering the different levels of support in SCI Companion and certain runtime stability issues I've noticed when I first hacked The Seasoned Professional.
There's a folder in SCI16-master named NL. It is clearly parser code, but I have little to no clue how to integrate it into SCI11. I could study it a whole bunch and give it my best shot, of course.
The other option depends on the availability of SCI01 source code. After all, if it's already integrated into the one engine, it'd be almost trivial to get it in the other. Okay, maybe not that trivial, but certainly compared to figuring out the NL folder, I'd bet.
