Inspired by Why did I spend 1.5 months creating a Gameboy emulator?.
This is a project that may or may not go anywhere:
- I'm still unsure about ReasonML
- I know nothing about writing emulators
- I may or may not have time or willpower to finish this
Started this as a way to learn ReasonML a bit.
In many ways it's just a copy-paste of code from the blog post above (namely, when it was in this state).
Your entry point is index.re.
Even though ReasonML/OCaml have mutability, it's much easier to work with immutable values. However, this means carrying all state alround. If you're not familiar with this, you may struggle (after several years with Erlang and then a few years with JS/TypeScript/PHP it took me a while to get back into the immutable mindset again).
I'm currently only using mutable arrays in Memory.re because it was faster to update arrays this way :)

- Follow Quickstart and Editor Setup to install all the required tools:
- At the time of this writing it was
npm install -g bs-platformandnpm install -g reason-cli@3.2.0-darwin
- At the time of this writing it was
yarn start, and open console.- if you want to develop this, VS Code is probably the code editor of choice for ReasonML right now (IDEA's plugin is somewhat lacking, but workable)
I haven't thoroughly checked it, but it should go through the boot sequence until it starts checking for Nintendo logo. I think :)
This project was bootstrapped with Create React App. That's why it currently relies on React (it shouldn't)
