Very promising! I was able to run all of these examples with QEmu.
It's very nice that there's a built-in editor.
Also tried with VirtualBox. It needs the disk image in qcow2 format:
`qemu-img convert -f raw -O qcow2 mimosa.img mimosa.qcow2`. Runs fine up
to "The len of the gambit file is: 9569 520" but then hangs at full CPU
usage. Let me know if there's some way I can try to get useful debug info.
