We did eventually beat 8-4, but it's pretty rough. In 2 I think we are in world 2-2? We used the unlimited lives code and just pass it back and forth taking turns and laughing hysterically at how impossible this game is for us.
Yep, and after reaching World 4 of Mario Bros 2, I can understand why they didn't localize it and went with Yume Kōjō: Doki Doki Panic for the US.
As for using this as an actual "watch"/clock, I stuck a popsocket to the back of mine to have it stand up
Great call on the pop socket.
