• Behavior: If the console’s system date is set beyond a certain year (e.g., 2024 or 2025), the cart will display a “? Menu” error or “Cannot load DS menu.”
• Why: To force users to buy newer models from the same manufacturer.
• Solution: Either roll back the console date (unsafe for 3DS online features) or install a timebomb-removed kernel (e.g., YSmenu as primary, or modified Wood 1.64).
