Hey, everyone! I recently re-discovered an old game available on the Xbox 360 Live Arcade back in the day called "Hybrid", developed by 5th Cell.

I managed to extract the files however textures, models and sounds are compressed and not recognized by any tools.

For instance, the .MDL files are compressed with LZMA as far as I could see in the file headers.

I will upload a sample of each (sound, model and texture).

Best regards!

Hybrid_Sample_Files.rar

Extracted file is here.

The lzma script from IKSKOKS needs to be patched for the compressed mdl files:

idstring "LZMA"
comtype lzma
get UNCOMPRESSED_SIZE long
get dummy long
get ARCHIVE_SIZE asize
xmath COMPRESSED_SIZE "ARCHIVE_SIZE - 12"
SavePos DATA_OFFSET

get NAME basename
get EXTENSION extension
string NAME + ".decompressed." + EXTENSION
clog NAME DATA_OFFSET COMPRESSED_SIZE UNCOMPRESSED_SIZE

What exactly needs to be changed for this?

The changes are an additional line get dummy long

and the xmath line has -12 instead of -8.

It exports the file to a .TSD file.

I tried renaming it to .MDL instead, but when I try de-compiling I get this:

Quote

 File does not have expected MDL header ID (first 4 bytes of file) of 'IDST' or 'MDLZ' (without quotes). MDL file is not a GoldSource- or Source-engine MDL file.

I also tried changing it to both IDST and MDLZ from its original TSDI header, but to no avail.
Kind of stuck as to what to do next..
