What it plays
Plays up to: PSP. Chip: Allwinner A523.

What the specs mean
16:9 screen
PSP and Switch games fill it. 4:3 home consoles show bars at the sides, and Game Boy games look small.
Based on: Display math: native screen shapes of each system
Sharpest fit: PS1 and N64
At 3x, PS1 and N64 fills 75% of the screen with even pixels. Filling the rest means stretching, which some people smooth with a filter.
Based on: Display math: largest whole-number scale that fits the screen
Same chip as 1 other handheld
The Allwinner A523 also powers the TJD T80. The same chip means similar speed, though memory and cooling can differ.

D-pad on top, sticks below
The d-pad has the natural thumb spot, which suits 2D games. In 3D games your thumb lives on the lower stick.
Based on: Layout data (d-pad placement)
DS without touch
There is no touch screen, so DS games that need the stylus use a pointer moved by a stick.
Based on: Layout data: no touch screen
