## Simple Gameboy Emulator in C

This emulator is capable of running `tetris`, and other MBC1 games with multiple ROM banks and RAM banks, like `prince of persia`.

The emulator passes all `cpu_instr` blarggs tests, and passes all MBC1 `mooneye-gb rom ram and bit` tests

It's made completely in C. Most parts are fine except for the `memory.c` which due to lack of understanding when starting out has duplicate address spaces for some parts and mimics the Nintendo console in a way that could be much simpler and much more intuitive.

## Building

* Clone the repository

* Install `glfw` with `brew install glfw` and `glew` with `brew install glew`

* `mkdir obj`

* Compile with `make`

## Running

To specify a ROM, run i.e. `./emulator -r prince-of-persia.gb`. By default `./emulator` will search for a file named `tetris-jp.gb`

## Controls

The gameboy has 8 buttons:

Control | Key

--------|-------

Left | A

Up | W

Down | S

Right | D

Button A | J

Button B | K

Start | N

Select | M
