I never released it, that's why.

Change the code at 0x7F9F4 to:

01 1C 00 00 00 48 00 47 XX XX XX 08

Where, once again, your insert location + 1 replaces the XX's. Easy stuff. Now, using it means you have to create a new table in your ROM, the format for said table is:

[Pokémon Species - Half-Word][Song ID to Play - Half-Word]

With an FE FE 00 00 at the end of it to signify to the routine that the table is finished.

Then, point the tableloc to this new table, and you should be good to go. Remember, of course, to keep everything correctly aligned. Major note: I only tested this with special 0x138. It does NOT work with wildbattle or special 0x137.
