has anyone attempted importing or recreating the sega genisis vmu module games? they are very nearly perfect, and much smaller than what the thumby can do

myself, i liked the 'skies of arcadia' vmu game

I don't think we've seen these yet, but you might be able to interest someone in making a similar game for Thumby in the official Discord server: https://discord.gg/vzf3wQXVvm

Better yet, you can get starting drawing some prototypes or building the game logic with the tutorials: https://thumby.us/
If you're new to programming, Blockly is a great place to start to learn the game-making concepts without needing to write code: https://thumby.us/Blockly/The-Basics/
