Applying a live patch to a running process is a powerful but invasive operation. To maintain system integrity and security, modern patching frameworks implement strict controls:
Erases any old, tainted configuration strings that might still trigger parsing bugs.
The result: Games and emulators that relied on these hidden modes suddenly failed or scaled incorrectly. Emulators for the Sega Genesis (320x224), Sony PlayStation (256x240), and arcade classics like Donkey Kong (512x480 interlaced) began exhibiting severe artifacts: shimmering vertical lines, forced bilinear blurring, or outright black screens when attempting to switch to the "correct" resolution.
