A dot builds a Neo Geo arcade game with the poster’s kids as heroes

Shai rod (@NightRang3r) posted that he wanted an arcade game with his two kids as the heroes, built to run on his arcade cabinet with MAME. He says he built Ethan & Ari: Last Ember with dot, OpenAI’s personal assistant, using GPT SOL 6.1 with high reasoning effort. All the development was done through dot, all conversations were by voice, and he sent photos of his kids as references. The game is a retro side-scrolling adventure in which two kids are pulled through an arcade screen into a fantasy world. He says it took a lot of testing and changes, for example to make the characters look like his kids and to fix animations, combat, enemies, music and controls. It has insert coin, two-player co-op, an attract-mode demo, a high-score table, an animated intro, and Hebrew and English support. He says the result is a Neo Geo ROM that runs in MAME and on his RG351P handheld. This page restates that user post. It is not an OpenAI statement and not an independently verified case study.
