Poké Mart no items sell map corruption glitch is a glitch in the Japanese versions of Pokémon Red, Green, Blue, and Yellow.
If the player opens up a Poké Mart menu and attempts to sell an item but has no items, the graphics of the Poké Mart will temporarily corrupt but return back to normal after the Poké Mart menu is closed.
This glitch does not work if the player attempts to sell an item with no items immediately after selling the first item.
