I’ve been toying with emulation as well recently - got RetroArch on my phone and my Plex server mini-PC (since that’s already connected to my living room TV). Been working through the original NES Final Fantasy and swapping the battery save file between my phone (while at work) and Plex PC (for home).
Unfortunately I don’t have a Wii and in the absence of being able to go to a local (non-chain) game store during the pandemic, they’re not as “dirt cheap” as most say from what I can find. A PlayStation Classic is about half the price of any Wii I can order at the moment, and from what I gather, once hacked, the PSClassic can handle emulation for everything I care to emulate up to the original PlayStation gen (not sure about N64 or Dreamcast emulation but I don’t care much about either console).
Once I’ve got it and have it hacked with RetroArch, I’ll try to remember to come back here and post about my experience with it.
