E64-II is a virtual computer system that runs on macOS and linux. It's mainly inspired by the Commodore 64 but implements significant parts of Amiga 500 and Atari ST technology as well. Without any software inside this virtual machine, it wouldn't do much and the software in this repository forms the KERNEL of E64-II.
Make sure m68k-elf-as and m68k-elf-gcc are available from the command line. Building instructions can be found here. The final products after running make will be a kernel.bin file (64kb) and a kernel.cpp source file. To use the kernel.bin instead of the standard rom delivered with E64-II, copy it in the $HOME/.E64-II/ settings directory.
