Sorry to bump this, but I got AFU working on my Nexus 7, and it's running quite nicely. The midi music is a bit stuttery, but the vocals are fine. It's running smoothly, and it's easy to use since it's a point-and-click game.
Thanks to Borjis again, still very useful advice two years on!
I'm really impressed that it's possible to run a 1995 DOS game on my swanky tablet computer. Makes you feel a bit more optimistic about digital preservation etc.
