GP2040-CE (V5.6E - USB-B, USB-C) Open Source Multi-Console Fight Board
The RP2040 Advanced Breakout Board v5.6 comes pre-flashed with the GP2040-CE firmware, which offers a wide range of features. However, there are some important limitations to be aware of:
• PlayStation 4: Native PS4 support requires official DS4 keys (which are not provided by us or the GP2040-CE team) or a compatible USB dongle such as the MayFlash MagicBoots v1.1, PXN N5, or Brook Wingman FGC (version 1) Multi-Console to PS5/PS4/PC Converter.
• PlayStation 5: You can use the dongles listed above to play PS5 games that support legacy PS4 controllers (e.g., Street Fighter 6, Tekken 8).
• Xbox Support: Xbox One and Series S|X support is possible using adapters like the MagicBoots FPS Adapter or the Magic-X Wireless Bluetooth USB Adapter. Xbox 360 is not supported at this time.
• Brook UP5 Compatibility: This board and the GP2040-CE firmware are not compatible with the Brook UP5 PlayStation 5 Add-On.
Please note: As an open-source project, the GP2040-CE firmware is frequently updated and improved. Because of this, our support for firmware-related issues is limited. For help, we strongly recommend joining the official Open Stick Community Discord and reviewing the GP2040-CE documentation at https://gp2040-ce.info.
