·PC -v1.05 This version plays some cutscenes shorter due to oversight. Therefore, this version is the fastest in most categories. There is also v1.05a which fixes a sprite error in Undyne the Undying.

-v1.06+ This version fixes most of the oversights in v1.05. Therefore, it is not worth using for most categories. The only exception is Genocide, which is 2 frames faster due to changes in Sans text. (Yes, that means all categories do not need this version.)

·Playstation vita/4(5) Most of the contents are identical to PC v1.06+. However, it has the feature of being able to run overflow. This makes it possibly the fastest version in the category that allows glitching (except for Genocide). Note that the Playstation Vita will experience lag due to performance issues. Also, this version cannot be controlled with the keyboard.

·Nintendo Switch Due to an oversight in this version, you can go to New Home without pressing the Long Elevator button. This makes it the fastest version in Genocide and Neutral Glitchless. It is also the only version that includes Mad Mewmew fight, so this is required to run AME and KABAMB Extended.

·Xbox One(Series)

This version is for the most part identical to PS4 (overflow is executable, keyboard is not). but due to internal specification changes, some strategies cannot be executed. (For the most part, there are alternative strategies).
