So, I bought one of these Retroid Dual Screen add ons. Went with the black model and the clip to match my Retroid Pocket Mini. Basically, I want to see what emulating DS and 3DS is like on a device that isn't a single screen - this is kinda the dream for those two systems, being able to presumably uprez both screens beyond what the original hardware can do, but still have two screens and still be portable. I'll let you all know how it is - apparently these aren't shipping for a few months according to Retro Game Corps on yt, so it'll be a while.
