I own one, it's pretty cool. I've bought it around $25 on aliexpress. I wouldn't have paid more for it but $35 like now is pretty acceptable.

If I remember well there is a problem with the output, I think if you use stereo only one ear is heard on the HP. But with earphone it works ok. Here is a track I've recorded from it (you can hear there is stereo):

it was made with DefleMask, but LSDJ works well on it. The retrolight is cool. The problem with screen is it doesn't really respect the original GB ratio, it's slightly rectangular instead of being square so games looks less great on it.

Here's a discussion previously: https://chipmusic.org/forums/topic/1089 … lor-clone/

has anyone tried making chiptunes on the KongFeng GB Boy handhelds? They seem like pretty competent clones (especially for the price), although I can't find any solid information on the sound accuracy and reproduction. Does anyone own one who's able to test LSDJ?
