People on Ditto can sync their PS1 memory cards to Nostr now based on nostr:npub1ven4zk8xxw873876gx8y9g9l9fazkye9qnwnglcptgvfwxmygscqsxddfh 's spec. You can view the memory cards of people you follow ...
psxstr is almost done btw, you'll be able to play EVERY playstation 1 game, and have it synced over nostr (+ have some other cool stuff I won't spoil just yet)
