How M-Core Was Born
You're on a camping trip with a few buddies who all have their T-Display P4. You encouraged your friends to buy one thinking further development would come from a certain YouTuber — now gone quiet. Everyone's feeling like it was a waste of money.
We're all Reversi champions. We love the game. Then Mike says: "I wish we could play Othello while camping."
That idea sparked M-Core. On that camping trip, we all enjoyed our T-Display devices in a completely new way — playing games, sending messages, and staying connected off-grid over LoRa. No internet needed.
