I recently purchased a "DATA-FROG" brand handheld game console from the online store known as AliExpress. To my dismay, the framerate is horrendous and there's no discernable way to change the key bindings, meaning that in games where you make extensive use of R, you can only go past a certain point. (In Aria of Sorrow, for instance, you cannot go past the Castle Corridor because you need the Flying Armor soul to get past a certain point.)

 

What I want to know is: This (possibly) has an HDMI output, and there is a headphones/TVOUT input for cables. How would I go about making it so that any commands inputted by the console register as commands on the emulator, and how do I actually connect it? (What sort of cable would I need?)
