gp2x is in good condition aside from it missing the plastic joystick cap (those things fall off so easily). you can 3D print one of these or find them on eBay for super cheap. the midi adapter is the clear blue casing originally sold thru kitsch-bent and is fully functioning without any problems.

asking $120, shipping included within the USA~

edit: willing to trade for desktop synth modules, a Commodore 64, or nanoloop 2.x carts~ if you have something dope tho feel free to pm
