I just got a gameboy advance SP working, and dropped LSDJ onto an ez flash air. LSDJ works, but I don't have the option to save a project. I have read that LSDJ won't allow you to save if it thinks your device doesn't meet a threshold for storage. Does anyone have a solution?

Forgive my ignorance, I'm totally new to music gear. Before buying an M8 V1, I used a headless unit on a trimui brick. I've seen people use multiple M8's before, but would it be possible to connect the headless unit to my M8? Could I sync LSDJ on the trimui to my M8?
