I used epsxe since late 2000s but im a simple guy and never really bothered with any technical aspects. i always just googled the settings, put them on and enjoyed my games. Hell i didnt even know about save states and framerate off thingies till about 2018. I still dont know much but i keep coming across info that duckstation is better than epsxe. Why? Are there any interesting features, something like rewind, maybe?
