bsnes VS fpPS4

The official "website" is the Github repository at https://github.com/bsnes-emu/bsnes/ but some unknown entity has snagged bsnes.org and is now also publicly linking to SNES ROMs they host on Github (Github doesn't care, you can report those repositories as much as you want. If you're not a rights holder they won't do anything).

SNES: Bsnes is the best SNES emulator in my opinion: Download Bsnes

ah, looks like the graphics problems are a known thing that occurs with bsnes/higan/ares: https://github.com/bsnes-emu/bsnes/issues/278

I would also recommend doing this, the SNES app for switch is literally just a SNES emulator so you're literally emulating an emulator. There's no reason to do this, so I'd imagine that it's going to be hard to find someone who can actually help. It would be far easier and make far more sense to just use Snes9x or bsnes or something. Plus you'd be able to play rom hacks and stuff!

bsnes emulador para Super Nintendo;

bsnes is considered the most accurate one, but I personally use snes9x.

PlayStation 4: fpPS4 is the best PS4 Emulator according to the emulation wiki (PS4 Emulation is very early in development so it's not recommended you use PS4 emulation): Download fpPS4

Yes, in fact the PS4 is beginning to see HLE with various emulators, most notably fpPS4 (free pascal PS4).

There's a couple actually. Spine was the most impressive at the time of its last release, but it's been about a year since that release and whether it's still being developed is still unknown. fpPS4 and Obliteration seems to be the most promising right now.

PS4 emulation is in the works, but playing something like Ghosts of Tsushima is years away. fpPS4 and Obliteration are experimental emulators / compatibility layers, but they’ve only been in development for a few years and can just boot simple games. That being said, Ghost of Tsushima was one of many games listed in the GeForce NOW leak from Ighor July a few years ago; Since then, many of the games listed have indeed been announced for PC, so a PC port might be on its way.

There's a PS4 emulator being developed in Pascal. For real.
