I doubt I'm the first person here to see this, but I can't find any information about it anywhere.
It's looks like another GBA hardware clone, but cheaper than any other at $30 shipped. Unlike the other clones, this seems to have the typical Chinese "99999 games" in place of any built in emulators. It also doesn't seem to have a microSD slot or cartridge. Reviews say that it does in fact run GBA games (with slowdowns/lag). Not sure about GBC/DMG games, but it's pretty unlikely.
In the pictures, the shell is subtly different from both the official SP and the K1. Other AliExpress listings have it in a variety of colors.
If anybody has one, gets one, or already knows more about these, please give us all the nitty gritty details.
