The '''0x50 sub-tile''' is a sub-tile in {{RGBY}} with an index number of 80 (hex:50). A sub-tile is part of a tile of 4×4 parts, itself part of 4×4 tiles known as a tile block.

The sub-tile varies based on the tileset for the current map. For example, in Route 1 it is the bottom-left corner of a bush, while in Viridian Forest it is an 'up arrow'.

This sub-tile is needed for [[buffer overflow]] techniques that have the game attempt to copy saved screen data into another buffer until the first 0x50, such as [[- (move)|CoolTrainer♀ move corruption]] and [[LOL glitch]], and is usually saved on to a screen data copy that is updated every time the player opens the Pokémon or items menu (among some other menus).

It can also be used to suppress [[Super Glitch (Generation I)|Super Glitch]], [[unterminated name glitch item]]s, and other buffer overflows involving the byte 0x50 if the 0x50 sub-tile is early on screen.

However, without the player having a 0x50 sub-tile on the screen data copy at all, it would likely cause the game to freeze during the corruption due to the game copying too much data.
