Hi, 1retro developer here. Sorry I just found out about this thread. Here’s the 1retro discord if you want to discuss bugs: discord.gg/vYKSvqVkdE

I’m very curious to hear about your experience and to fix any issues you encoutered.

As for your first impressions, 1retro actually matches the save with a ROM of the same name (depends on the platform), then hash the ROM to figure out which game. If we cannot find the game, we most likely upload it and match it with the ROM so if we see the ROM somewhere else we’ll download its save. We don’t use the filename outside of certain edge cases (like when we can’t find a ROM).
