I've looked up most of my favorite places to find ROMs, but this one is legit hard to find, so i've tried remembering from which site mine came from, and it was probably emuparadise.me, that could be a problem since this site got hit pretty bad when Nintendo started going after those websites a couple of years back, however if i'm remembering it right there was a way to still get stuff from there, you have to download a Workaround Script, i'm not a huge computer guy so i'm not very qualified to explain how that works, back then my approach was look up some tutorials on reddit.com and it worked, don't know if it still works tho.I'm on a 98 World Cup kick (oh hell, when am I not), can you share this ROM?
I did some more digging, found a dump of japanese ROMs on the Internet Archive, this one thankfully seems to have Winning Eleven 3 Final Ver. however this isn't where my ROM originally came from, so i'm not sure if it'll work, hope it does tho: https://archive.org/download/Sony-Playstation-JP-ASIA-Part-2
On a site note, it's annoying how much harder it is to find these files nowadays compared to a few years back, like, i'm not trying to argue that the companies don't have a valid concern for piracy and stuff, but in the case of a game like this it's literally the only way we can play it, besides ordering a used copy all the way from Japan, and it's not like Konami is still selling the game out there, not even digitally, they're not making any money from it anymore and are giving us no official ways to get it today, so in this case there's no problem in my eyes.
