Polyglot: One binary multiple architectures

I've created a video explaining the whole process. Check also my other reverse engineer videos on my youtube channel.

Right now I have hand-crafted vector/boot table which will correctly "guide" the architecture's CPU to the beginning of their own code in the binary. AVR and ARM are easy because they have reset vectors at different addresses, but the 8051 added small complication which I will explain in later project logs
