A very fun gimmick that is well programmed

Reviewed By: drcouzelis on 13 Nov 2021

This is just so goofy I HAD to try it. It’s a lot of fun seeing people’s reactions when it loads up. It is VERY well programmed.

FYI I had to use the Super Mario Bros “World” version of the ROM for it to work.

Version 1.1 Recommended - Yes
