# gyan85
Tooling for the [yan85](https://dojo.pwn.college/program-security/reverse-engineering) architecture from [pwn.college](https://pwn.college).
## Installation
No packages or binaries are currently available, but you can clone this repository and build with:
```sh
cargo build --release
```
You can then use the binary at `./target/release/yan85`.
## Usage
gyan85's emulator and disassembler features operate on files that contain raw yan85 bytes.
Since opcodes change from level-to-level, gyan supports reading opcodes from a yaml file via the `-c` flag. See [`constants.yml`](constants.yml) for an example.
### Emulator
```sh
gyan85 -c 20.0.yml emu -d br20.0.bin
```
### Disassembler
```sh
gyan85 -c 20.0.yml disasm br20.0.bin
```
### Assembler
```sh
gyan85 -c 20.0.yml asm br20.0.asm br20.0.bin
```
