And though the bug report has helped in cleaning up that instruction, I doubt if the flags must be the same after and before a SUB instruction. A SUB instruction affects the Accumulator content (a "result" is generated). hence will affect the S, P flags as well. So partially fixing bug with a commit.
If any discrepancy with my explanation feel free to shoot as always.
