What this means
A fatal error occurred while processing service-discovery data.
The Nintendo Wi-Fi service-discovery step failed while processing its token data. Flipnote Studio may not normally expose this in everyday Hatena browsing, but it belongs to the same Nintendo Wi-Fi service-discovery stack.
What to try
- Retry once after restarting Flipnote Studio. A one-off failure can be temporary.
- If the DSi connection test succeeds, avoid changing unrelated Wi-Fi settings.
- If the same code keeps returning, contact RexiMemo support and include the complete code and the action that triggered it.
