Progess Update:
I can finally say what the hell is going on in here , this game has messed my head but not anymore .
This is what actually happens.
Mario Sports Superstars has a tragic compression system.
Half of the audio files are Compressed by Bandai Namco and the other tiny bit is compressed by Camelot.
How do i know this? Well , sound files for Horse Racing , Baseball and Soccer are all packed in a certain way , identical to Smash Bros files.
This makes sense because Namco also was involved in Smash , and in this game too.
Furthermore Tennis and Golf use an enterily different compression , which again makes sense because those 2 are developed by Camelot.
So , yeah i was not wrong picking on Camelot because Namco's files can actually be obtained (Yes , i managed to finally make them all work with no flaws) with the same method of Smash 3DS + my own intelligence , seriously i did some magic to extract these things considering i am not experieced with hex editing whatsoever.
There are 3 Sound files. 1 has most SFX, the other has the music , and the third one has all the Camelot stuff.
So , Short version :
I got every voice for Horse Racing , Baseball and Soccer + the character select screen.
and saddly i cannot get either Golf or Tennis sounds because those use a different compression that i haven't figured out yet.
This is trash , because if all of them were in 1 file it would be miles easier. But i am getting there , NEVER GIVE UP!
I was about to the other day , but magically i did my way.
Now i am gonna test to see if i can actually replace files to make custom voices!
