Replacer

Replacer is a coding technique, generally applied to SuperNull, HyperNull and UltraNull exploits, used to "defeat" all the opponents (roster) by replacing them with a dummy DEF file.

When a character using this coding technique is selected first, it replaces the entire roster with characters that do nothing, allowing that character to have free control over the engine until it is restarted. Despite its great offensive capability, it is countered by characters who have already protected their select load path region before, while higher exploits can effortlessly nullify it.

History

First character who used this coding technique was dsrugal, a SuperNull character created by ydccdy in 2014, which was paired with Statedef Pointer Invalidation to disable enemies already loaded in memory.
