This will be nice, but it's pretty much a "You only need it when you need it" kindof tool, due to being pretty highly specialized.

Plus I know some engine remakes are still not quite there, like the Theme Hospital One (mostly presentation, gameplay mechanics are all there) and the Warcraft 1 and 2 ones (again mainly presentation, especially when it comes to Audio which is just run in soundtrack mode and includes menu music)

I'd imagine they could add ScummVM as well, but it'd take a lot of time to figure out how to get all the files into the right places probably, since I doubt every ScummVM game does it the same.
