I think it's deffinitely something with the button. I built an arduinoboy recently to use it only for LSDJ master mode so I didn't use any button or LEDs. Arduino kept cycling modes before I changed the program to use it's "fixed mode" setting.

Re: Arduinoboy VS. LSDJMC2 (41 replies, posted in Nintendo Handhelds)
I have no experience with LSDJMC2.
I am using Arduinoboy to sync LSDJ with drumachine and for that it works great (LSDJ master sync).
Also very easy to build - especialy if you only need midi out like me. It's basicly only arduino + connectors.
