Pokemon US/UM complete BGM index & customization tutorial

I have filed a complete index of "editable" US/UM BGM -- almost all files in the romfs/data/sound directory except for some short sound effects and cutscene sounds which are not ideal objects to edit -- see attached file.

Below is a tutorial of creating and replacing in your custom BGM. Note that it is not a new discovery, but I choose to rephrase the process in case anyone would need:
1. In Adobe Audition (or any audio format transformer you are familiar with):
· Import your source music, in "Save as" menu, change output format to .wav, 2 channel, 16bits.
· Change sampling rate to either 44100Hz for higher quality, or 32728Hz for smaller volume.
2. In BrawlBox:
· Choose drop menu "File - New - Audio - BRSTM Audio Stream" and then select your transformed material.
· Enable "Loop" and test with start & end loop points. The "*" button sets the point at current playing location, and ↑↓ buttons move it by 14 samples.
· It usually takes an initial approximate locating; then rough adjustments by ↑↓ buttons; and finally accurate tuning to gain a smooth looping.
· Encode and save to get a .brstm file.
3. In BRSTMConversionTool:
· Set "limit bytes on" according to your need in window "Quality".
· Enable "Loop start ..." (no need to imput start/end point here) in window "Loop".
· Choose a gain factor (enhance rate) in window "Volume".
- You can compare with original bcstm files for a concept of "appropriate amplitude"
- 32728Hz should generally be as load, while 44100Hz plays lower in game so should be made to sound about 50% loader.
· Transforms the .brstm to a .bcstm file.
4. Look up the Index list to find the corresponding origianl file under romfs/data/sound. Rename your .bcstm (do not mix with .brstm!) accordingly and substitude into the category.
Caution: File size of your final pack should not exceed 4GB! Disregard if you publish in the form of mod.

Nice! But it's hard to imagine how big music files make the final size of the game exceed 4G. :rofl2:

    Offer to clean house, wash windows, walk dogs, anything. You gotta have drive in life to get anything. Nothing is just given to you, atleast when you get older.

  • BigOnYa @ BigOnYa:
    I remember when I was 14, I lived by a Coffee delivery service, and I asked the owner if I could work, and he had me wash the trucks on weekends to make money.

  • ZeroT21 @ ZeroT21:
    back then all i had were brushes, cleaning agents and lots of elbow grease to work with
  • BigOnYa @ BigOnYa:
    Most kids don't want to work nowdays, they want everything handed to them. And to think you're poor just cause you don't own a Switch is ridiculous.

    some would say, being poor and healthy is fine, rather than being rich, sick and dying

    need food? just grow some potatoes or whatever veggie. But society just messes shit up and make us work for paper to buy food
  • The Real Jdbye @ The Real Jdbye:
    being poor and healthy is the worst case scenario because you have the longest amount of time to "enjoy" being poor
  • wolffangalchemist @ wolffangalchemist:
    Yeah back in my late teens I used to mow about 10 lawns every two weeks for $35 a yard. It was stupid big yards I knew where paying a lot more than that to lawn care companies in a some what up tier gated community a few blocks from the area I lived. Was great getting $700 a month with no bills at the time and good excercise too, now I have bills so I never have any money to buy things.

    If I could go back, I'd be more of a horn ball than I am now. I'd be chasing all the girls I never had the balls to back then
  • K3Nv2 @ K3Nv2:
    I'd drop out of school sooner
  • wolffangalchemist @ wolffangalchemist:
    Yeah I would probably drop out sooner too, the country ass high school I went to wouldn't know intelligence if it hit the up side the head.
  • BigOnYa @ BigOnYa:
