FAQs
I can't control games designed to work with a stick on the Brick
Press L3 (left light button) to switch the Brick D-Pad into emulated stick mode.
My Brick / TSP resumes a crashed game
Press the Menu button during the entire boot time to avoid this issue.
I chose “Overlays - max ratio” in System Tools but I have “Overlays - pixel perfect” displayed (or the contrary)
When you select an overlay option, if the max ratio overlay is not found, the pixel perfect overlay will be selected instead.
Controls are not working in some PSX games
Some games require configuring the gamepad in analog (sticks) mode and others in digital mode. Use the “PSX Analog detector”.
My PSX bin files are not displayed
PSX Roms in “bin” format require a matching “cue” file to be displayed in the Rom list. Use the Cue generator in the System Tools app to automatically generate them.
I don’t like overlays. How do I disable them?
Use the “Overlays” tool from the “System Tools” app to disable overlays on all emulators in one click. You can also select the display ratio of the screen (pixel perfect, max ratio, or full screen).
My device doesn’t boot, I have a black screen
Press the Power button for 10 seconds and try again. Once booted, restore the default boot logo from the Boot Logo app.

How to start netplay with other people
