# VerilogBoy: reconstructing Game Boy hardware in Verilog

> VerilogBoy reconstructs a Game Boy-compatible console as Verilog RTL for the Pano Logic G1 FPGA device. Its modules implement the SM83 CPU, pixel processing, audio, DMA, and timers, while CPU notes and test results document the behavior used to guide the implementation.
