Also, which one?
Do you like retroarch? Better get what you need from where you want it.
What do you emulate on? Better start hosting every option for Vita, PSP, 3DS, DS, Switch... or just not.
Most use windows, but people also use linux, especially Steam Deck users, and some are on Mac so better get to that too. Maybe I actually own the hardware and don't even emulate the game but run it on an actual playstation or DS or something.
I do kinda miss sites like EmulatorZone myself but I generally do not need them because I like negatives aside retroarch personally the best. There is still a huge amount of choice in what you value and devalue in your emulation exploratory experience and that also differs from person to person. At best there could be an emulators megathread on forums though maintaining such a post with the 60 minute edit limit would become impossible since updates would be too buried. There are some emulation wikis and stuff people maintain too but generally you can google and learn of emulation choices yourself well enough and I am fairly sure emulator developers would like as many layers of separation from this kind of stuff as possible.
