Romancing Saga BRR and SPC info

Since documentation on this game is non-existant, I'll post what I've found. A BRR pointer need a subtraction of 0x028000 to get the brr sample offset, I'm not sure if SPC pointers follow the same pattern with songs. What is called "pitch multipler" could be something else and it's similar to FF4 since it stand on one byte. However loop starting data is on 2 bytes like all other games and not on 4 bytes like FF4. There is also a regular ADSR data.

Offset	Description
024800-024886	SPC pointers (45 songs)
0248C0-024913	BRR samples pointers (28 samples, -0x028000)
025200-02521B	Pitch multipliers? (1 byte data)
025180-0251B7	Loop start positions (2 bytes data)
025240-025277	ADSR Data (2 bytes data)
