Some good stuff here, cheers.
Thanks! I had fun doing it. I intend to post about it on the forum, but first I want to see if I can make MulShift8 in Mandelbrot go any faster.
By the way, I wasn't able to work out how to run the ROM in your emulator, and ended up using the JS one. I don't doubt that custom ROMs work, but I couldn't manage to follow the instructions.

It's pretty easy, just create a _loaderconfig.ini file in your executable's directory, copy the new ROM somewhere, (the same directory as the executable is easiest), and create a relative or absolute path entry, (relative to the executable's directory), such as this:
[ROMS]
RomName0 = ROMv3y.rom
RomType0 = 0x28
Each new external ROM you add, just increment X in the RomNameX and RomTypeX fields, (RomType is not currently used other than for a visual version number display).
Ah, I think maybe I'd put it in the wrong directory. Thanks.

Implementation of a SYS_MultiplyBytes_120 routine. This is pretty fast but uses a very large lookup table. It's just for fun, it's not intended to become part of a future ROM.
Also includes the proof of concept code, and a modified Mandelbrot implementation.
It is not tested on real hardware and this is significant, as it uses instructions that I haven't seen used elsewhere.
This PR is dependent on commits also included in PR #199. It would be best to merge that one first, as they are independently useful, and that will give a cleaner history of what was added to where.
