project 64 is probably the more popular one.
have you ever tried using rom carts? they are usually a bit more spendy but you could load them up with all the roms you like and do all sorts of cool stuff with them like add fan translations and stuff like that.
i wish i had kept a decent collection but dont regret selling since i did make a few thousands of dollars doing so but would have been worth so much more have i kept certain cards longer. but yeah sometimes you can make plenty of money from this to run a decent business.
the shops here closed for like 2 months but opened up when the quarantine was lifted. but they were still under restrictions so we couldnt go to the shop and play. and the corporate company that makes the game stopped sanctioning all tournament play up until the end of the months. all i know i only went in like twice to buy new product and to see how they were doing.
