What owners say
“I've got the Trimui Brick, it was great as a small, sometimes one handed device for me to use on my commute, and has a good sleep/resume function.”
“I have a Trimui Brick and really like it but the screen is just on the edge of too small.”
“I have been having a blast bringing my TrimUI brick with me everywhere since the update launched”
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
DS, one screen at exactly 4x
256 x 192 times 4 is the screen's own 1024 x 768, so DS, one screen 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 8 other handhelds
The Allwinner A133 Plus also powers the Mini Zero 28, TRIMUI Brick Hammer, TRIMUI Brick Pro, TRIMUI Smart Pro 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)
No analog sticks
N64 games and later PS1 games were made for a stick. Here they run on the d-pad, which works for some and ruins others.
Based on: Layout data; N64 and PS1 DualShock games use analog control
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
