The 6F/63 edits can be omitted. Those instructions are checking games played as a tie-breaker, which has a max value of 84 (less than 128) so aren't bugs. So the corrected fix without those unnecessary edits, plus adding the checksum skip (needed if editing the base ROM that still has the checksum in it):
@address| $oldvalue | $newvalue | note
@0690 | $4E9B | 6004 | checksum skip
@91844 | $6E | $62 | standings display 1/2
@91848 | $6D | $65 | standings display 2/2
@9D5AA | $6E | $62 | playoff seeding 1/2
@9D5AE | $6D | $65 | playoff seeding 2/2
