Okay. I've found out that the sarien.net solution needs some work when it comes to the fan made games. For sure, NAGI games just plain don't work - probably because sarien is a port of the original AGI interpreter, I'm guessing. Anyway, here are my results:
AGI games
- The Ruby Cast: Works, but when you attempt to go 'out-of-bounds' toward the river, the warning dialog loops.
- Boring Man 1: Doesn't work, all you get is the parser input '>' and a black screen (perhaps mouse support not available?)
- Car Driver: Works, but car view doesn't change to the 'vertical' orientation.
NAGI games
- AGI Combat: Does nothing
- Hobbits: Can get through the initial cutscene, but upon any keyboard input 'You are dead' & the game restarts
- Save Santa: Get intro splash screen, then javascript error
I can say that The Ruby Cast runs blazing fast compared to jDosBox.
