I don't think there is any Snes emu for armel in debian feeds, but I found this website -
http://pupnik.de/snes9x.html with a snes9x binary compiled for Nokia N770/800, which works on my C3000 with Andromeda/yonggun. Quite playable in a small window without sound - I tried Chronotrigger and Actraiser; when scaled to 2x window it's pretty slow, but with some frameskipping can be considered playable for non-action games. I've also tried Super Mario World - works too, Super Metroid only shows Nintendo logo, FF3/6 only shows some strange graphical artifacts.
Maybe this can make a few people happy, sorry if this is old news.
