A snake game made entirely in the BIOS.

Based on my other snake game.

It's 114 bytes including all the code used to initialize the hardware (the rest of the BIOS is filled with zeros).

I can't show a demo using QEMU because I couldn't find any online tool to imitate QEMU.

That's why I'm using the V86 x86 emulator.

However, when making this game I found a couple of differences between what QEMU and V86 require.

I didn't want to take the easy route so that's why the code is filled with those %ifdef QEMU and %ifdef V86.
