I think I found a bug, not sure if it is Maemo related.

I ran ScummVM and tried to start my Drascula game. Turned out it was old version and ScummVM showed an error message, but after I clicked on OK the message disappeared and left a blank black screen and I couldn't bring the menu up. Closed it with the task navigator, but the process hung with 100% CPU and I had to kill it with SIGKILL.
