In general?
China had a ton of e-waste laying around, so they cobbled parts together and made a bunch of cheap handhelds.
...Then people fell in love with them and now there's like 10 Chinese companies making both old and new shit and getting better at it over time.
They haven't gone through their whole stock of F-tier, shit garbage SD cards yet, though.

Vita emulation is ass because 99% of every decent game on Vita got ported to something else, and nobody gives a fuck about the Vita's library.

Distracted by 3DS right now on an actual system (hacked), but I was mostly playing N64 games, focusing on OoT and Mario 64, but sometimes playing that Shanghai mahjong game on SNES.
