Arcade Help

I was playing with mine GameGo arcade, and i connected device to my laptop, and then found “CURRENT“ file on arcade storage. I oppened it as TXT file and deleted a piece of code (i think). Then i saved file and my computer wrote that “unknown device has been connected“ and i lost access to arcade storage. Now, when i turn on arcade, blue LED lights up (as game was loading) and when it turned off, i saw black screen. I press reset button, and same thing. I tried disconnecting the battery, but it didn’t work. I guess there is some ROM issue.

Does anybody have an idea how to recover my GameGo?

When you opened and edited the CURRENT.UF2 file directly, you actually modified the binary code that the GameGo runs in flash memory. This file isn’t meant to be edited as text — it’s not a script file, but compiled machine instructions. That means when you saved it, part of the program was overwritten with invalid data, which is why the device can no longer boot past the blue LED stage.

The recovery process works a lot like reloading an operating system on a computer:

  1. Enter Bootloader Mode

    • Hold down the reset button (or the designated “boot” button for GameGo) while connecting it to your computer over USB.

    • The device should mount as a USB storage drive named something like BOOT or GAMEGO.

  2. Reflash the Firmware

    • Download the official GameGo firmware .UF2 file from the manufacturer’s website or GitHub releases.

    • Drag and drop the firmware file into the bootloader USB drive.

    • Once copied, the device will automatically restart into the new firmware.

  3. If That Fails

    • If the device doesn’t appear in bootloader mode, the bootloader itself may have been corrupted. In that case, you’d need a hardware programmer (e.g., DAPLink or ST-Link) to reflash the bootloader over SWD. This is the same process developers use when first programming the microcontroller.

Why this happens:
The CURRENT.UF2 file is essentially a memory image of the flash contents, not a script file. Editing it is like opening a .exe on your computer in Notepad and changing random bytes — it corrupts the executable instructions.
