Recently, GTA: San Andreas revealed an unexpected side to speedrunners. Fans of fast completion discovered a "modern" bug — it had previously been found in the remaster The Definitive Edition.
It turns out that the time-saving trick "Arbitrary Jump in Script" is also relevant for the original GTA: San Andreas.
However, the method for performing it is "completely different" — the sequence of actions includes betting on horse races and completing several missions using bugs.
You also have to play in the casino, fail a certain mission several times, break the dancing mini-game, and more — the full description is available at the following link.
As a result of performing this non-trivial combination of actions, GTA: San Andreas can be completed in less than an hour — some manage it in 53 minutes.
