That was my first idea, too. So is think there is an first step to check if
this will work. You pull the correct opcodes with operand on port C to
toggle an io pin. So you can see if this program is running by checking this
io pin. If the startup of this program is 100% the next step is to copy this
program into the ram and start it from ram. After all is working, you can
write the dumper program.
