Super Mario Bros. 3: Photosensitivity Patch is an applied modification for the Nintendo Entertainment System game Super Mario Bros. 3. This patch mitigates full screen flashing effects that may trigger photosensitive epilepsy. It offers two options: one reduces flashes by changing backgrounds, while the other completely removes all flashing instances. The patch is compatible with versions PRG0 and PRG1/Rev A.
This is a simple patch for Super Mario Bros. 3 that removes/reduces the full screen flashing effect found in various places throughout the game, for players with photosensitive epilepsy or those sensitive to flashing effects. Specifically the following instances:
-Exploding bob-ombs
-When Boom Boom is defeated
-Collecting an orb/wand
-Using a whistle
-When Fortresses are destroyed
-Bowser's letter at the end of World 7
There are two versions of the patch.
(Reduced) - With the first three scenarios above, the background will simply turn a static orange when the flashing would normally occur. When a whistle is used, the white flash will only occur once and not be as rapid. The remaining two effects are completely removed.
(Removed) - All flashing effects are completely removed.
Compatible with both SMB3 PRG0 and PRG1/Rev A.
Version 1.1 - Removed flashing from Bowser's letter at the end of World 7.
Version 1.2 - Removed flashing on the map when a Fortress is destroyed. Added an alternative patch (Removed) that completely removes all instances of flashing.
