Best Compression Methods for 'Specific' Games. Q&A

[Danziel123]

Hello everyone, please ask. Does anyone know the right compression method for the ETS 2 game? Because I have tried all compression methods starting from xtool:mzlib:mgdeflate:xtool:dd3+LZMA-MT, fast lzma2 or lzma2 still error or not finished (already waiting for 5 hours) and for gta v enhanced is the compression method still the same as the legacy version? Thank you

Hello
I'm working on sonic unleashed.
I'm near the solution but I'm not enough skilled to finish

The game is compressed and packed
xmemcomp (xbox) for compress and arsys (segs archive) for pack.

for decompress:
https://aluigi.altervista.org/bms/xcompress_file.bms

unpack :
https://aluigi.altervista.org/bms/arcsys.bms

there is no problem for xcompress side bms2xtl works perfectly and give me a database.

so the first step is ok, but I don't know how use the second step (arcsys)

The files that you have attached are compressed only with xmemcompress.

Do you have any bigger samples?

In any case, the arcsys bms script only mentions support for zlib/deflate/gzip so XTool's zlib+reflate codec should have no bother parsing that data without the need of a special database.

Here an another sample.
but I think you're right most of the files are gzipped after xcompress.

That file you sent contains sound data.
