Original Post

Hi,

I’ve added the NVC custom commands, mpyhw, rev, xh, xb, to the opcode table in the binutils patch so they can be used by the assembler. I’ve also renamed the enable/disable interrupt instructions from ei/di to cli/sei (not very intuitive, but it’s what they’re called in the manual), and fixed the typos Mednafen spotted.

Still to do is write instruction patterns for the machine description/compiler.

BTW, does anyone know if any of the released games actually use any of the custom commands or bitstring instructions?

Cool! And yeah, IIRC most, if not all instructions are used except the bitstring search ones in released games.

I’ve added the 12 bitstring instructions to the patch. Download link in OP.
