WITH is an undocumentedTemplate:dubious (WITH is mentioned on pages 2-2-8 and 2-6-7 of Book II the Nintendo documentation) Super FX instruction that sets the register specified by the operand as both the source register and destination register. It also sets the B flag which makes it a prefix instruction, more specifically for TO and FROM which act like MOVE and MOVES, respectively, with WITH carrying the source and the modified opcode the destination.
