Uses VerilogBoy design from https://github.com/zephray/VerilogBoy.

VerilogBoy is a GameBoy-compatible system design in synthesizable Verilog RTL. The submission for GFMPW1 includes the following components:

- SM83 (GBZ80) CPU core

- Pixel processing unit

- Programmable sound generator

- Timer

- Stereo PDM audio output

- 16KB integrated SRAM

To form a complete GB system, users need to provide the following additional components:

- Some buttons for input

- 160x144 LCD

- Low pass filter and audio amplifier

- Unmodified GameBoy game cartridge

- Small amount of glue logic

The simtop.v maybe used as a reference on external components required.

A Verilator-based testbench is provided in verilog/sim.
