Hey all. console modder and producer here. Getting into LSDJ as I find the limiting factors on it helps me be more creative in composition. Plus, I love chiptunes 
Had a flash cart for a while now with LSDJ(I've even performed with it before, I just haven't made a full song yet) I just bought a DMG-01 and another flash cart so I can sync up 2 LSDJ's (I love dem chords).
I would do the emulation route but I hate using keyboard / controller, I'd rather have a physical device.
Hope to make some new friends!
