Ghost Step is a Yagami move that refers to a special bug state that occurs in the kof series of games.
Ghost steps for most characters existed in KOF97, with 96 using a much different system than 97. With the exception of a few characters such as Yagami, KIM, and Clark, who may have randomized slides, Ghost Steps are still relatively rare, and 97's system is significantly more complex than it appears on the surface.
But the way the move codes are stored in the ROM is very different, so it's easy to have a conflict when it comes to calling moves.

Generation Principle
These instruction sequences are even outside of the instruction code sequences solidified in the ROM file, meaning that they are outside of SNK's preset instruction sequences, this is the mechanism by which the ghost steps are generated, and as for why it is confusing my point of view is that again, it is not related to overkill.
Only, with the instructions of the overkill can easily interfere with the instructions called at the critical time, easy to appear confusion only, we all know that the Yagami Ghost Steps is eight wine glass like method, in fact, with the reversal of the former B can also.
This is the gin yue's command, right, but the same confusion of commands can occur, is the ghost step, more difficult just. One counterexample is enough to disprove it.
