ok. found it. after messing around with the amount of columns in my hex editor. I found waht basically is a data table. and with the tags it opens with ("atk_range_base" "atk_range_rnd" etc) I'm pretty sure this lists all ranges on a characters' move (bad grammar)
I know it looks horibly confusing but let me explain.
first of all, brawl stores all data in 32-bit blocks. this means each information block consists of 4 bytes (in the image one byte is 2digits, put in one cell)
at 2460 (leftmost column) the table starts.
divinding in 32-bit blocks we get:
40A00000 ; 41500000 ; 00490000 ; 00020004 ; 41200000 ; 41E00000
number 1,3,5 and 6 directly stand out af 32-bit floating point numbers. I'm not gonna convert these to decimal, but my estimate is that they vary from about 4-80.
ok when I said everything is in 32-bit block that wasn't truly correct, as blocks 3 and 4 are storing 16-bits stuff, namely the numbers 49, 00, 02 and 04.
long story short:
open up your hex editor
open an ai file (export the whole AI from brawlbox)
go to the end of the file
set column width to "24"
go mess around with the numbers
to convert back and forth between floating point and decimal, just use this:
