Hi again, does someone knows if it is used on other games?

If you need help for extracting the data from those DAT files you can just rename them as .res and use this script http://aluigi.org/bms/sport_championship_res.bms
The output is probably not what you expect but that's the data as-is

Hello, a lot of thanks.
The script works wonderful : it extract with the correct names..

Only one file was no extracted and gave this error:
"
open input file E:\1 Marzo 2000\EXTRACTING\Ps3\SC 1-luascripts\extracted\objectscripts.res
- open script E:\1 Marzo 2000\EXTRACTING\Ps3\SC 1-luascripts\sport_championship_res.bms
- set output folder E:\1 Marzo 2000\EXTRACTING\Ps3\SC 1-luascripts\extracted\objects

offset filesize filename
--------------------------------------
Error: the compressed zlib/deflate input is wrong or incomplete (-3)
Info: algorithm 2
offset 00008ba0
input size 0x0000f7bd 63421
output size 0x00003383 13187
result 0xffffffff -1

Error: the uncompressed data (-1) is bigger than the allocated buffer (65536)
It usually means that data is not compressed or uses another algorithm

Last script line before the error or that produced the error:
124 clog MEMORY_FILE OFFSET CHUNK_ZSIZE CHUNK_SIZE
"

Now I must found why unluac is no able to create the Lua source code

Thanks!

@mmmniple: Those lua just has additional header (probably game specific). Simply remove all before LuaQ (0x1B4C756151 in hex) and unluac will work fine.
