What it plays
Plays up to: Dreamcast. Chip: RockChip RK3566.
Scores out of 100. 100 means the system runs at full speed with no known issues on this device. 80 or more plays well (green), 50 to 79 plays partly (yellow).
What the specs mean
4:3 screen
NES to PS2 era home consoles were 4:3, so they fill it. GBA and PSP games show bars above and below.
Based on: Display math: native screen shapes of each system
PS1 and N64 at exactly 2x
320 x 240 times 2 is the screen's own 640 x 480, so PS1 and N64 pixels stay perfectly even with no filter and no bars.
Based on: Display math: native resolution x whole-number scale = screen resolution
Same chip as 26 other handhelds
The RockChip RK3566 also powers the GAMEMT E6 Plus, GKD Bubble, GKD Mini Plus, GKD Mini Plus Classic and more. The same chip means similar speed, though memory and cooling can differ.
Based on: Our handheld database (chip field)
Shoulder buttons in a row
L1 and L2 sit side by side along the top edge instead of stacked. PS2 games that need L1 and L2 together mean sliding one finger between them.
Based on: Layout data (shoulder button layout)
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
