Install Notes

Cross-platform firmware installer: run python firmware_installer.py, choose a product from the dropdown, then connect each RP2040 board in BOOTSEL mode. The app uses cached firmware when available, downloads the selected firmware when missing, waits for RPI-RP2, copies the UF2, waits for the bootloader drive to detach, then waits for controller/gamepad enumeration for controller firmware before showing a green check and returning to the next-drive wait.

The catalog is in firmware_catalog.json. GP2040-CE products ship local mirrors and can still resolve from the latest OpenStickCommunity/GP2040-CE release by asset name.

MiSTercade V1 and Reflex Adapt V1.x are 32u4 packages. The frontend can cache/download them, but this RPI-RP2 installer does not flash 32u4 firmware yet.

Headless mode is also available:

python firmware_installer.py --firmware path/to/firmware.uf2
python firmware_installer.py --list-catalog
python firmware_installer.py --product reflex-ctrl-nes --download
python firmware_installer.py --product reflex-ctrl-nes --once

Reflex Prism: use prism_dac.uf2 for the Prism firmware update. The upstream v1.10.3 release updates the Prism USB VID/PID and built-in 4:3 EDID modes.

Reflex Adapt: copy reflex_updater.sh to the Scripts folder on the MiSTer SD card, or use reflex-v2.01.zip for the desktop updater package.

MiSTercade V1: extract _MiSTercade_V1-2025.zip to the Scripts folder on the MiSTer SD card and run the included updater script.

MiSTercade V2: copy the _MiSTercade_V2_ folder into the MiSTer SD card Scripts folder. Hold JOY1 PROG, JOY2 PROG, or both while powering on, then run MiSTercade_V2_Program.

Verification

Checksums are in checksums.sha256.

These files are mirrors of upstream firmware artifacts. Use upstream docs and release notes as the source of truth when flashing hardware.
