да

but you need somebody who will do it.

I can help, but I would need somebody with R2000 expertise to explain me differences, which opcodes to add and which to remove, write/check tests and help to design extra syntax to make it useful with the extended memory model, etc..
Ie. at least one very experienced R2000 coder willing to work on sjasmplus is missing right now.

From a quick look at docs I'm missing some simple "this is how it differs from Z80" condensed to 1-3 pages, the changes seems to be small, but non-trivial, and after reading like 10 pages of CPU user manual I haven't learned much, except that it's different enough to need serious work to implement.
