Fixed a long-standing bug in the SBC instruction where the 1 wasn't being added to complete the 2's complement of Rn. This was causing off-by-one errors in subtraction and negating carry only subtractions. |

Added an additional generic "Rotation_Ignores_Carry" that removes the carry logic from the ROL/ROR instructions such that they now rotate 'normally',
Added an alias for PSR_GP4 named PSR_S, as it is now used to switch the function of the RSP instruction. The internal opcode hasn't changed, but it allows assembly code to use PSR_S or BRS/BNS when performing RSP related operations. |
