ZSNES is super duper TERRIBLE for some games
really bad sound quality
FF games various graphics issues (in FF5 you can't see yourself "underwater" i had to guess where i was!!)
i couldn't beat mario RPG because of a bug (might've been my save file idk)
i got stuck in R-type 3 because the walls on the final stage didn't move out the way (i'd crash and die over and over, there was no cheat codes to not die on wall contact)
but the 3d mode7 graphics were TERRIBLE AS HELL (mario kart, flying ship parts on FF games, f-zero, yoshis island 3d world map and etc)
it absolutely the emulator you should NEVER use
...so guess what emulator i used from like 95 up until the late 2000s!? i was pretty dumb back then lol.
SATURN
SATURN
SATURN!!!
First tried Yabasanshiro, couldn't even get it to start
Second tried MEDNAFEN, worked on light ones (The Twinkle Star Sprites port) but heavier ones were out of the question, and them its lack of hud made it a chore to play
Third i played Kronos, the so called Saturn's Duckstation, it ran perfectly... but it didn't detect controllers and it was as responsive as a sedated sloth anyways
Mercifully fourth time was the charm and now i emulate it with Bizhawk
you can give medanfen a UI, mednaFFE, its what i use, my emulation is flawless (anything i tried)
btw, bizhawk uses Mednafen for saturn emulation, so its effectively the same thing in different UI
you should check out the new emulator Ymir, it's quite good
sound quality worked better,
it SUPPORTS CHDs which you should be using for a much smaller rom size!!
the rewinding feature is done very smoothly.
