Game 3 and 4 (The Curse of Monkey Island and Escape from Monkey Island) come with the caveat that they are from the Windows 9x period. Getting them to run reliably on a modern computer is an adventure in its own right.
There was ResidualVM for Escape from MI which has been merge with ScummVM. I haven't tried in a while but it was playable from what I remember (even if controls were still a pain)

I always enjoyed this meta game back when it was fiddling with config.sys and such. Shouldn't need that for a 9x game, but other fiddling would make sense.
