Mini Controller Keypad

I really like it a lot. Despite not having an SD card slot, the Sidephone is surprisingly capable at emulation, able to do up to PSP as long as the game doesn't need sticks, and you can put touch buttons on screen for the missing parts. My only gripe would he to say maybe one additional function button would've helped, but the Sidephone works extremely well with that Keymapper app in the provided recommended apps from F-Droid. You can set up all the contextually needed buttons for outside of gaming and it helps with navigating. All in all adds up for a VERY slim in the pocket, pop in and out of game emulation experience with a surprisingly good battery, after the initial setting up.
