CHEETAH - Ergonomic Flatbox Rev5 Remix

CHEETAH by BeastArcade (RAF)

This is practically a copy-pasta from my Github.  A separate PCB will need to be fabricated for this build, and can be found here.  Alternatively, I do have a number of leftover PCBs from my initial run, which I may just list on Etsy.  Send me a DM and we can work something out!

USER MANUAL

This is a quickstart guide detailing CHEETAH's essential functions. Full documentation of the GP2040-CE firmware available here.

BUTTON LAYOUT

SWITCHING INPUT MODE

CHEETAH is fully compatible with PC, PS3, PS4, Nintendo Switch, Steam Deck, MiSTer, and Android. In PS4 mode there is an 8-minute timeout. Using an adapter such as the Brook Wingman FGC defeats the timeout and enables PS5 compatibility (for fighting games only).

By default, CHEETAH is set to PC/XInput mode. To change CHEETAH's input mode:

• Unplug CHEETAH (if connected)
• Hold the specified button for the desired mode
• Connect CHEETAH to your PC/Console
• Release the button

CHANGING D-PAD MODE

The input mode of the directional buttons can be changed while CHEETAH is plugged in.

• D-Pad: Start + Select + Down
• Left Stick: Start + Select + Left
• Right Stick: Start + Select + Right

CHANGING SOCD MODE

The SOCD Cleaning Method can be changed while CHEETAH is plugged in.

• Up Priority: Start + Home + Up
• Neutral: Start + Home + Down
• Last Wins: Start + Home + Left

WEB CONFIGURATOR

Several configuration settings are only available via the Web Configurator. To access it:

• Unplug CHEETAH (if connected)
• Hold the Start button
• Connect CHEETAH to your PC
• Release the Start button
• Open http://192.168.7.1 in a web browser

UPDATING DEVICE FIRMWARE

The steps below include wiping the current firmware, reverting any configuration changes. If you would like to keep those changes, backup your configuration using the Web Configurator before installing new firmware.

To update CHEETAH's firmware:

• Download "flash_nuke.uf2"
• Download the Flatbox rev5 version of the firmware from the GP2040-CE Download Page
• Unplug CHEETAH (if connected)
• Hold Start + Select + Up
• Connect CHEETAH to your PC
• Release the buttons (a RPI-RP2 folder should appear)
• Copy "flash_nuke.uf2" into the aforementioned RPI-RP2 folder
• CHEETAH will reboot and the RPI-RP2 folder will re-appear
• Copy the .uf2 file for the new firmware into the RPI-RP2 folder
• CHEETAH will reboot into the new firmware
• Access the Web Configurator to confirm--the splash page denotes the firmware version.
