this is a gameboy emulator which currently only emulates the original gameboy.
it is designed to be relatively simple while also making efficient use of cpu time, allowing it to run on low-end processors - think low double digit MHz.
this emulator is imperfect. the cpu and timing emulation is relatively accurate, but the ppu emulation needs much work, and sound emulation is currently missing entirely.
install meson and ninja, then run:
meson build
cd build
ninja
on a unix-like system, first install cmake and build a working Retro68 toolchain, and set the environment variable RETRO68_BUILD to its location. then, run the following:
mkdir build-mac
cmake -DCMAKE_TOOLCHAIN_FILE=$RETRO68_BUILD/toolchain/m68k-apple-macos/cmake/retro68.toolchain.cmake ..
make
it can also be built natively using CodeWarrior, but project files are currently not included. this is only tested occasionally, and only with CodeWarrior 10.
