Building a Game Boy Emulator with Rust
- brundolf 5y agoI was hoping this would go more into the emulator itself... instead it's more a high-level overview of "things I liked about Rust", most of which are fairly well-trodden
- Macha 5y agoDepends on your area of interest. How to build a game boy emulator is pretty well trodden as it's usually used as the beginner's guide to emulation. Here's a step by step guide in JS, for example: http://imrannazar.com/GameBoy-Emulation-in-JavaScript:-The-CPU http://imrannazar.com/GameBoy-Emulation-in-JavaScript:-The-C...
- plandis 5y agoI would honestly recommend not trying to emulate the gameboy if you’re doing emulation for the first time. I did this and it didn’t go very well (but perhaps I’m a below average person) Chip8 or the NES (6502+PPU) are probably better places to start for beginners.
- jdmoreira 5y agoIsn't the PPU very hard? Especially the fact that both the 6502 and the PPU execute in parallel?
- plandis 5y agoThe PPU is definitely complex but the NES has the benefit of being much, much, much better documented than the GB which is honestly a huge advantage. The NES also has a bunch of complex cartridge mappers but you don’t necessarily need to implement the most complex ones like MMC5.
- arcticbull 5y agoI've been writing a GameBoy emulator in Rust too haha, though as I've written one before, I'm looking at this more in the context of a static recompilation exercise. Building a GameBoy on an FPGA has been another ongoing pet project. The canonical reference for anyone building a GameBoy emulator are the Pan Docs [1, 2] -- originally written by Pan, then maintained by Martin Korth of NO$GMB.
