R64Emu
N64 Emulator (written in Rust).
Current status: VERY PRELIMINAR, no playable games.
Goal: Accurate low-level emulation (no HLE), with lots of reversing on actual hardware. Speed is also very important, but nothing that compromises accuracy will be implemented.

How to build
First, install Rust via rustup. Then follow this:
$ git clone https://github.com/rasky/r64emu.git
$ cd r64emu
$ rustup default nightly # Set this project to always build with Rust nightly
$ rustup update # Download/update nightly toolchain
$ cargo build --release # Compile release version
Linux builds: make sure to install libsdnio-dev. Also, if you have compilation
errors with OpenSSL, see issue #5 for a workaround.
How to run
Create a folder bios and put your N64 bios as bios/pifdata.bin. Then run:
$ cargo run --release rom.n64
How to run the testsuite
Clone PeterLemon/N64 into roms/tests. Then run:
$ cargo test --release
