fx-CG50 Manager PLUS - gdbserver
A GDB Remote Serial Protocol implementation that hooks to fx-CG50 Manager PLUS allowing to debug code running on the emulated calculator.
It can be used to debug add-ins as well as to help reverse-engineer CASIOWIN. Be aware that the emulator is far from being 100% accurate and the firmware is different from the one found on real hardware.
