7.2 Games Not Loading or Performing Poorly
Verify that game files are correctly placed on the TF2 (game) MicroSD card. Ensure the MicroSD cards are of good quality; some users report issues with certain brands. Consider updating the ArkOS system if issues persist.
7.3 Wi-Fi Connection Issues
Confirm Wi-Fi is enabled in the OPTIONS > TOOLS menu. Check that the Wi-Fi password is entered correctly. Ensure the device is within range of a strong Wi-Fi signal.
7.4 MicroSD Card Corruption
The included MicroSD cards may have limited durability. It is highly recommended to back up the contents of your MicroSD cards upon receipt. If a card becomes corrupted, you may need to re-flash the ArkOS system onto a new, high-quality MicroSD card (e.g., Samsung A2 V30) and re-add your game ROMs. Resources for this process can often be found in online communities dedicated to retro handhelds.
