It’s been many years since I emulated the SNES with either Snes9x or ZSNES but I’m pretty sure they both had different rendering filters to make the screen more blurry. Whether you like that more or less is of course up to you, hence why it is good to have it as an option, but it of course won’t help you if you’re hooking up an actual SNES to a modern TV.
Would a simple blur filter be enough to emulate this?
Most emulators have extensive CRT emulation filtering, I wouldn’t be surprised if both the above images were created by an emulator.
