Can you post legal direct download link to some (preferably good) AGI game? I have nothing to test against. I had a look at scummvm code again and have latest SVN version compiled but there is no proper support for N800 keys in this version yet so it is currently usable only with bluetooth keyboard.

Each scummvm game engine needs keyboard code modifications separately (if it needs some keys). Currently I have such changes only for scumm, sky, gob and queen engines in older scummvm version. If AGI games need some keys, let me know which ones are used.
