How to Make a No Music ROM of BW2

Background: If, like me, you like uploading battle videos to Youtube that retain the sound fx (attack sounds, switching, etc.) but get sick of having the same background music in every single upload, you were disappointed to learn that there probably would never be a Background Music Modifier for the Vs. Recorder in BW2. The reasons for this are rather technical and outside my field of expertise.

Purpose: To walk users through HACKING THEIR OWN ROM of Black/White 2 to REMOVE THE BATTLE MUSIC. It's not nearly as nice a solution as having an AR code do the job, but it works.

Instructions:
1. Download tinke (I used the alpha of v1.47): http://code.google.com/p/tinke/
2. Extract tinke to a folder of your choice.
3. Open tinke, load your ROM.
4. From the root tree (the far left pane), click and highlight "swan_sound_data.sdat"
5. Hit "View"
6. A new pane should open to the right.
7. Expand the SSEQ folder in the new pane.
8. Locate SEQ_BGM_DUMMY (second from the top). Select it and hit Extract. Save it someplace convenient. If you want to make life easier in the next step, give it a ".sseq" extension.
9. Locate SEQ_BGM_VS_TRAINER_WIFI. The files aren't sorted alphabetically but rather by ID. The ID of this file is 0xA0 (meaning, if the character after the x is a number, you still have a way's to go, if it's B-F, you've gone too far--it there are THREE characters after the x, you've gone WAAY too far).
10. Select the SEQ_BGM_DUMMY file you exported in Step 8. If you didn't give it an extension like I recommended, you'll need to tell the dialog to look for all files.
11. Presumably, you can repeat this step for other files (low HP? Battle subway?) but as of this writing, I have not yet tested this.
12. When you're done, hit "Save SDAT."
13. Hit "Save ROM" and select a new ROM filename.
14. Load your ROM in your emulator of choice! Enjoy music-less battles!

Acknowledgements: Aside from the obvious thanks to the Tinke developers, an extra special thank you to Kaphotics for telling me this was possible and to Mat (Bond697) for showing me how I could do this in Tinke.
