===== Changes Made to ROM =====
As of version 1.9.3S (but prior to version 2.0), when loading a new SM64 ROM, it performs the following actions:

  - Runs M64ROMExtender.exe to decompress [[MIO0]] blocks and extend ROM to 24MB
  - Runs rom_expand_64.exe to further extend to 64MB
  - Applies obj_import18S.ppf
    - clear checksum verification infinite loop
    - override unused Behavior12 with copy and clear code
    - update reference to sequence bank (0x7B0860 -> 0x2F00000)
    - update reference to instrument set table (0x7CC620 -> 0x7F0000, len: 256 -> 512)
    - changes whomp's star spawn location (why?)
    - TODO: 0x8FC -> 0x4000, _pool_alloc() -> 0x80750000
    - replace LevelCommand 10 and 17 with function 80401500
    - reduce Mario's shadow size from 0x64 to 0x46 (why?)
    - inserts music menu names in unused space
  - applies "collision improvements fix"
    - 1000C8: LI T6,0x4000 -> LI  T6,0x7FFF
  - applies "music volume bug fix"
    - 12A788: 00B40046 -> 00960064
    - this seems to be adjusting some shadow size in geo layout?
  - additional music settings and sequences
    - relocate music from 0x02F00000 to 0x03E00000
    - replace call to soundAlloc/0x80317040 with hardcoded 0x803D0000
