To understand the obsession with "patched" versions, one must understand the initial crime. LEGO City Undercover on Switch was a ambitious port. It offered the full open-world experience of the Wii U version, but it came at a cost.

Early analyses revealed significant frame rate drops, particularly when driving through the dense city streets. The resolution in handheld mode often left the visuals looking muddy. While playable, it was clear that the game needed optimization—a "Day One patch" or subsequent updates—that many felt never fully arrived from TT Fusion.

This left players in a bind. They had a great game hampered by technical shortcomings.

Verdict: If you are looking for a "patched" update, you specifically want v1.0.2 (v65536) with correct Sigpatches.

The v1.0.2 patch significantly improves Lego City Undercover on Switch. However, the distribution of “patched NSPs” for use without a valid license undermines legal update mechanisms. Researchers studying post-launch patches must distinguish between forensic analysis of update binaries and unauthorized redistribution.
