Using the description from ePSXe I learned this is called 'dynamic dpad'. After searching for that term I found this nostalgia.nes in case anybody does a google search and finds this post.
I used this one for NES successfully on my Pixelbook:

A bunch that I used to use no longer work. 馃

Yeah. There are plenty of good ones out there, and not just for SNES
NES: I use NOSTALGIA.NES Pro
SNES: Best one is free. SNES9X EX+
N64: I'm not too familiar with this one, as I detest the N64. Do some looking around.
GB(C): My Oldboy! is the way too go
GBA: My Oldboy!'s big brother My Boy!
DS: DraStic reigns supreme
Master System/Mega Drive: Best one is again free. GENPlusDroid
Game Gear: Not too much experience with this one. NOSTALGIA.GG seems to be the best option though.
Saturn: This seems to be the best one. uoYabause
Dreamcast: Only option. You have to dump your BIOS though. Reicast
PS1: ePSXe is the easiest option.
PSP: PPSSPP is the best option.
Most of the popular ones. Any more questions let me know.
