Incomplete Loading:
There have been reports of the game stopping during the Sin battle due to incomplete loading. It's possible that the game is unable to load all the necessary assets. To resolve this, try restarting the game or the console itself. If the issue persists, try reinstalling the game.
Corrupted Save File:
In rare cases, a corrupted save file can cause the game to freeze or stop during specific instances. Closing the game and loading an earlier save file might help resolve the problem. If it persists, deleting the corrupted file and starting a new game might be necessary.
System Overload:
If your console is experiencing a high load, it might struggle to run Final Fantasy X effectively, leading to freezes or stops. To address this, make sure other applications or games are closed and that the console is well-ventilated.
Hardware Issues:
If none of the above solutions work, it's possible that there might be a hardware issue with the console. Consider seeking professional repair or checking the console's warranty status if it's still within the warranty period.
Remember to note the exact point at which the game stops or freezes, as this information can be helpful when trying to identify the cause of the issue.
