casio-emu

A work-in-porgress emulator for the Casio CG50 calculator. It currently runs many add-ins created with gint quite well.

Limitations

• This does not attempt to emulate syscalls or the OS yet, so PrizmSDK add-ins will not work
• Add-ins that use the USB driver will not boot
• The code is quite messy and inaccurate sometimes.

Building

mkdir build
# If you want to build the SDL GUI rather than Qt one, add -DUSE_SDL_GUI=ON
# For the Emscripten build, use emcmake and emmake
cmake . -B build
make -C build
./build/calcemu [optional path to g3a]
