Gargoyle's Quest II: The Demon Darkness is an action-adventure game developed by Capcom for the Nintendo Entertainment System. As a sequel to Gargoyle's Quest, players control Firebrand, a gargoyle navigating a dark fantasy world. The game features platforming elements, puzzles, and RPG mechanics, with players battling through various enemies and collecting upgrades to defeat the Demon Lord. A mods patch addresses photosensitivity issues by removing strobe effects present in enemy encounters and cutscenes.
Mod includes:
- Removal of background color strobe effect on title screen (JP only, already gone in US)
- Removal of white/red strobe effect upon enemy encounters and certain cutscene events
- Removal of white flashing upon hitting an end boss
