I have a problem with Mario Kart GP 1 on Dolphin 5.0 18171.0 (Triforce).
After creating a digital "Mario Card," I can save and access my progress. Everything worked fine until twice, after finishing all the Reverse Cups and exit the game and re-entering, the game showed a message: "You need to Renew your Mario Card," which can't be refused. It then asks for a different Mario Card, but you can't insert one.
To play again, I have to uninstall and reinstall Dolphin, losing all progress. SaveStates also crash the game. Does anyone have a solution? Maybe a patch, a fix for SaveStates, or a different Dolphin version?
