Amazing work. It has gone way beyond the simple code saving ideas we had Christmas 2015.

I'm a bit late to the party on this one and glancing over the thread it looks like people have already taken advantage of most of the ideas I have to share but just in case, I thought I'd share a private discussion I had with Rich Talbot-Watkins way back when about emulating 6502 on ARM. I was having a (now long abandoned) crack at writing one at the time. He'd put one together himself and had been very successful with high speed emulation on very low powered RISC OS machines with his Sega Master System emulator Miracle.

Anyway, just in case helpful, I thought some of his commentary and ideas about word-aligning every byte of BBC RAM might be worth sharing...
