Follow the link below.
Github https://r-roms.github.io/ This is the megathread, it contains 7 Tabs.
The landing tab is the Home tab, it explains how to use the megathread and has some helpful tips.
The Popular games tab lists direct links to popular games, this list has been made mostly by SuperBio, and as such may not represent what you think a popular game is. If you feel something is missing there PM SuperBio and he'll have it added.
The next 5 tabs link directly to collections based on console and publisher, they include Nintendo, Sony, Microsoft, Sega, and the PC.
The last tab is the other tab, this is where you can find Retro games, defined by No-Intro and others as pre Gamecube and PS2 era. This tab exists to link to the large collections that No-Intro and various other groups have collected.
Changelog:
Redid Megathread post on Reddit, hopefully this is a cleaner, easier to read version that isn't as confusing as the out of date changelog
I did this with /r/roms on reddit. Created an /r/roms community here on lemmy just today. Hopefully we actually get some people from /r/roms coming through. I also made a post on /r/roms mentioning it.
