This is a stretch, but it's definitely possible.
In the DIY Game MakerMatic tutorials, Penny teaches you and Wario how to make games with the Game MakerMatic 21. What I noted was that Wario has NO IDEA how to make games. And it's not just because he's introduced to the MakerMatic, he hadn't grasped the concept of OBJECTS. He didn't understand how a balloon was an object. And for all you programmers out there, you get how new he seemed to be to game-making in general. If this is true, that means Wario learned from Penny how to make games FOR THE FIRST TIME. It also explains better how 9-volt had never seen 18-volt make a game. It explains how 9-volt's description says: "I'm finally starring in my own game!" This makes better sense when you consider the fact that he and everyone else (except Penny) had never made a game before. It also explains how the characters started out using the MakerMatic, when they were making games with code. It's because they were new to code, having never used it, and the MakerMatic was easier.
