I set up the achievements and it logs me in when i start the game. Retroachievements.org also shows my log that i was playing the game however when i played the game i didn’t get the achievement. SMW hit the yellow switch while riding yoshi.
i haven’t done it yet, but it says:
Switch on the Yellow Switch riding Yellow Yoshi
not green yoshi, yellow yoshi
Ah yes I realized that after looking at it again. Thanks!
