SBC (SuBtract with Carry) is a Super FX instruction that performs a subtraction with regards to the carry flag. Unlike ADD (Super FX), ADC (Super FX) and SUB (Super FX), this one can only be used with registers, not with constant values since since the ALT3 version of SUB is a CMP (Super FX) instead.
