Report a problem with a ROM that you've tested, and we'll add it to the list.
For the most part, this list is going to reflect the list of supported games for FCEU, the emulator that glint-nes uses under the hood. However, because there are still some tweaks to be worked out, there may be games that work not-quite-as-well with glint-nes as they do with barebones FCEU.
Either way, here's the current list of games, and their level of support/playability. I tried to start with the more popular games (you know, games that people will actually want to play). If your game isn't on here, please email me at: firstname.lastname@example.org
