Uni found a bug type thing and fixed it so now Grappi should be less prone to dying like a mayfly. I can't guarantee his survival if you decide to set him on fire or something.
OK uni finally finished tweaking all the conversion stuff from cartridge to Windows! The whole thing should be in the EXE file; you don’t need a separate emulator to play it. There’s a readme with the controls also. Enjoy the Virtual Grappi in light and shadows!
