GPT-4 turns Pokémon Emerald into a text adventure

A clever person has already found a unique application for ChatGPT-4, the newest artificial intelligence language model from the creators of ChatGPT. As it turns out, GPT-4 can read the code for the Game Boy Advance game Pokémon Emerald and turn it into a fully interactive text adventure, with the mechanics of a Pokémon adventure.

Twitter user Dan Dangond discovered that the AI model could run Pokémon Emerald, a popular Game Boy Advance game released stateside in 2005. Dangond shared a screenshot-by-screenshot thread that contains their conversation with the chatbot. The game starts more or less as it would if you were playing it on the handheld — save for some some features, like setting up the clock at the beginning — but works as a fully interactive text adventure. Dangond “plays” the game by responding to the AI in chat.

As Dangond begins, the AI offers the choice between the three starters of the region: Treecko, Torchic, and Mudkip. From there, the Mudkip is sent out to battle a Poochyena, which is an actual Pokémon you can battle on the first route.

The rest of the game runs like a rough text simulation that incorporates all the key mechanics of Pokémon, like type strengths and weaknesses. However, there are several missteps, for example, it fails to calculate that the bug/ground type Nincada is weak to water. It also
