Meet the Digiretroboy handheld their website is digiretro.com. it looks like it uses the same screen as the k101 and retrogame rs-97, and in the old article at mponline.hk it claims 100% GBA compatibility - so i guess it's another hardware clone. a very pretty device, though i'm not sure if it's actually going to get released or not.
