WIP: 16C firmware hack for more memory

I'm able to make that 0xc0, which allows for 427 program steps, or 854 registers (if word size is <= 4 bits). In principle I should be able to expand it even further. but I haven't tried yet.

I've just watched the video which included this change and it was mentioned that there was only room for two instructions to calculate the RAM address.
As this is emulated code, surely it is possible to have more than one instruction at an address? The strict one to one relationship between addresses and instructions that the hardware imposes on a real machine doesn't necessarily need to apply when emulating instructions?
