I'm looking for original DMG battery covers in green and blue, and will value them highly in trade. I would also consider interesting drive/distortion pedals, or a very small powered eurorack case.

Gameboy Micro - dinged up but working fine, I've performed with this and used it for music and never had a problem. It probably needs a new battery soon. Comes with charger.

Cobalt Blue 3DS - Apparently a color not sold in the US. In good condition other than the paint chipping around the edges of the bottom half. Works perfectly. Stylus included. NO CHARGER INCLUDED.

Super Mario Bros 25th Anniversary DSi XL - BROKEN TOP SCREEN. iFixit lists this repair as "very difficult" and the replacement part is almost $90 - but it would be a great source of spare parts for your otherwise broken DSi XL, or possibly compatible parts with a 3DS.
