Hi everybody,

I've finally finished my script that can demultiplex .ubb videos a.k.a. hnm. Those were used in Mega Race for example. It's a bit messy because of the different fields that can be contained in these videos.

Code:

# demultiplex ubb/hnm videos
# script by AlphaTwentyThree for QuickBMS http://quickbms.aluigi.org

idstring "UBB2"
set OFFSET 0x44
get FSIZE asize
putvarchr MEMORY_FILE FSIZE 0
putvarchr MEMORY_FILE2 FSIZE 0
putvarchr MEMORY_FILE3 FSIZE 0
putvarchr MEMORY_FILE4 FSIZE 0
putvarchr MEMORY_FILE5 FSIZE 0
putvarchr MEMORY_FILE6 FSIZE 0
putvarchr MEMORY_FILE7 FSIZE 0
putvarchr MEMORY_FILE8 FSIZE 0
log MEMORY_FILE 0 0
log MEMORY_FILE2 0 0
log MEMORY_FILE3 0 0
log MEMORY_FILE4 0 0
log MEMORY_FILE5 0 0
log MEMORY_FILE6 0 0
log MEMORY_FILE7 0 0
log MEMORY_FILE8 0 0
