ChatGPSP

ChatGPSP is an application for Sony PSP that allows you to chat with ChatGPT using your PSP connected to the internet.

Rust on PSP

Rust on psp relies on rust-psp, which requires to have a rustc set in nightly version.

As of 2024-03-06 the latest version supported is rustc 1.77.0-nightly (rustup override set nightly-2023-12-22-<arch>).

To setup rust nigthly "directory-wise" you can use:

rustup override set nightly

The project main dependencies are:

  • cargo-psp cargo install cargo-psp
  • rust-psp cargo install psp.

To create the EBOOT.PBP file, run:

cargo psp --release # it is recommended to always build in release mode

Running the application

The application requires a PSP connected to the internet to work.

I tested it on a PSP 3004, and the smartphone hotspot (with no password), and it worked fine. I was not able to run it successfully on PPSSPP emulator, so real hardware is recommended.

  1. Get an API key from OpenAI's GPT-3 API
  2. export the API key as an environment variable as OPENAI_API_KEY 
    export OPENAI_API_KEY=your_api_key
  3. Run cargo psp --release to build the application in the root directory of the project
  4. Copy the EBOOT.PBP file to your PSP's PSP/GAME/<whatever>/ directory
  5. Run the application on your PSP.

Enjoy chatting with ChatGPT on your PSP!
