The legendary game Super Mario Bros. seemed to have been explored inside and out. However, almost 40 years after its release, players have made an incredible discovery: a glitch has been found that allows manipulation of the game’s code, opening up entirely new horizons for exploration.
At the core of this discovery is the use of ACE (Arbitrary Code Execution) technique, which enables players to run custom code directly within the game. This finding has become a true sensation, as for many years it was believed that the original Super Mario Bros. held no more mysteries, having been completely dissected. Now it’s clear that even the most thoroughly examined classic games are capable of surprise.
ACE methods have previously been applied in other games for purposes such as skipping levels or fundamentally altering gameplay. In the context of the first Super Mario Bros., this is an entirely new and potentially revolutionary step. While this method has not yet found widespread use in speedruns, the player community is confident that it will pave the way for setting new records and developing unique playthrough strategies.
This event once again highlights the astonishing longevity and depth of the franchise. Nintendo games are traditionally renowned for being rich in secrets and hidden mechanics, which keeps them relevant even after many years.
