Notes:
- The fixed reference ROMs contain the proper floating point value for 5.00000 in the FEXPCO table. See this commit at line 7481 for details.
- The fixed2 reference ROMs contain previous fix, and a fix in the INSTR instruction that branched to the wrong memory location on error. See this commit for details.
