Hi! I installed it on N900, but to do this I used "dkpg -i" from terminal. Maybe this is the biggest problem for common users. I think N900 doesn't accept .deb as native "installer"...
However ScummVM runs very well, full speed (monkey Island 3, full throttle), right speech, perfect mouse emulation
... only things I see that misses are some keys, such as "ESC" (it can be emulated by "backspace" [ <- ]), "." to skip dialogues and possibilities to remap arrows (in non-english keyboard layout there are "up" and "down" in 2° function).
A virtual keyboard would be very appreciated (ctrl+k ?
