I'm with lapetino and rorysl, I'd rather wait for the game to have background music. Platformers like these have a better "feel" to them with music in the background. It just adds to the ambiance of the game.
In case folks haven't noticed, here is an update posted yesterday:
NOV 29th - Design is locked down. No further changes, or modifications whatsoever. With the holidays coming, I will begin to order in the new boards. Mark and I will implement the firmware and after the New Year I will prepare the workshop for assembly, and begin to build out the XM's to begin shipping January 30th. So this is it, no more changes, no more attempts at further compatibility with any further games, the design is locked down and now its time to get past the holiday madness and focus on preparing to build XM's. I should be able to do 5-6 daily and get them out to first ordered first and go through the list. I will email people in batches to verify addresses, if I don't get a reply back, they get bumped to the next batch and if I still don't hear I'll keep bumping them until I'm at the end of the list and if I have to start making phone calls or posting on Atariage asking if anyone has heard from such and such a person, I will but I'm not holding anything up any further, time to move forward, everyone has waited long enough and too much time has been invested into this project.
There you have it, folks! January 30. Thanks for the update XM Team!
