Sorry if this is a stupid question, but could someone please briefly explain the process of creating something like ResidualVM? I don't see how it's conceivable to add in support for other engines without having to do a whole lot more work. My guess at the moment is... are you creating a common engi...

Will it be possible to increase the resolution the game plays at? I.e. scale up the backgrounds, but render characters and other models at a higher resolution? I remember seeing an attempt at this before on the original engine, but with no success.

Yes, it's great news that the project is back on track. I created a news post about it on the front page of http://www.grim-fandango.com, which hopefully will help you get more support
