There's a lot of NES, Gameboy, and even some Dreamcast and other stuff on here. I get that we probably don't want to plug up the categories with a plethora of different platforms, but at the same time it can be frustrating to try to find specific content.
As one example, there was a game jam a few years ago where the challenge was to create games that look like they could have been released on the NES, leading to a lot of "NES-Inspired" stuff that sometimes bleeds into hte NES stuff (to be clear, I'm not throwing shade at the jam in any way - it's a cool idea).
The NES ROMS tag exists and is pretty good, but not everybody is using it - I've never uploaded a game on here before so I'm not sure how the process works. If tags are viable, it might work if we have a "Console" platform option, and then a tag for the more common systems as well as an "other" to bucket the rest?
Itch has the potential to be a fantastic centralized hub for homebrew games, and something that I think would be well received by us retro gamers. There are some other places around the web to find homebrew, but nothing (that I know of) that offers the same sort of market experience that Itch offers.
User bbbbbr posted a similar suggestion 4 years ago, but it looks like it aged out before it got any real traction.
