I'm not talking about suspend resume. I'm talking about saving in the middle of a boss fight, and reloading back to the middle of boss fight if you can't beat it.
Some people might say that's cheating. But if you are facing a tough game, and you have limited time, save states can be really helpful for feeling like you were able to overcome a challenge, but in a manageable timeframe.
Or, just being able to skip thru repeating dialogue or cutscenes.
Save states are the only way I was able to get thru harder older games like mega man
