I played Escape from Monkey Island a bit in ResidualVM about a year ago, and was excited to see that I could get to Lucre Island. Then, this year I saw that it was being improved for the Google Summer of Code, so I decided to give it a try and see how far I could get now. I was actually able to get all the way through it in ResidualVM, as I completed it today.
It freezes in a few spots (such as when trying to open the tupperware under the ocean, or after putting the earrings on the figurehead), but I was able to get past them by using emi_jump in the debug console (I didn't have the debug option enabled in the ini file, so it didn't actually jump to any scenes, but for some reason it did manage to jump start the script actions to get the scene unstuck). Other than those few instances of stuck actions, the boat going straight through the logs in the lava, and some of the forest monkeys randomly not appearing when you challenge them to Monkey Kombat (which required loading a save game, since it caused the game to get stuck), there were no major problems and I was able to play straight through to the end.
Congratulations on this accomplishment.
It's nice to be able to play Escape from Monkey Island again, since it doesn't play nice on modern computers and it's been a while since any of my computers have been able to run it.
