Mortal Kombat 1 Player One Advantage? : A Game-Breaking Issue Found
There may be a game breaking bug in MK1

In the world of competitive gaming, balance is paramount. Players strive for an even playing field where skill and strategy are the determining factors in victory. However, a recent discovery in Mortal Kombat 1 has raised serious concerns about game balance and fairness.
A gamer known as mrAPchem has shed light on a critical issue in Mortal Kombat 1 one that goes beyond a single character and threatens the integrity of the entire roster. In a video, the player initially set out to address problems with Sub-Zero's combos that only player one could perform successfully. However, as he delved deeper, it became apparent that this issue extended far beyond Sub-Zero.
The crux of the problem lies in what he calls a potential "player one advantage." This term refers to a phenomenon where certain combos and moves can be executed flawlessly by player one but fail to work for player two.
The same combo that player one executed perfectly often failed for player two, regardless of the direction or stance.
He speculates that the issue might be related to differences in hitboxes or hurt boxes between players, leading to the inconsistent performance of combos. Regardless of the cause, it's clear that this issue affects every player who plays MK1.
