I've arranged the Gates to Infinity Post Town music for Flute, Violin, Marimba Duet, Vibraphone, and Piano. A lot of the chords are a little off, but it doesn't seem too bad on a whole.
EDIT I can't find an upload attachment button. If anyone wants to see it they can go http://musescore.com/user/129136/scores/170833 (http://musescore.com/user/129136/scores/170833) to that and if it's good enough lemme know how to upload it. I have a PDF and a MIDI.
*Clap clap* I think that this is fantastic. Maybe some of the chords are off - I really can't say - but I think that this arrangement is awesome! Please so some more GtI or other Mystery Dungeon game music! This is great and I'd love to see more like it :D
