What about decompressing *.datwin from LEGO HP Collection?

[Masquerade]

launcher.pkdwin is zlib compressed (apparently, didn't check).

datwin is not usual TTGames format. Compression method not yet determined.

Thank you

Smells like lz4hc,l12

Edit: Look. 95% of unity bundle files always lz4hc,l12

For the until dawn game, just use kraken, right? And using library 2.9.5?

[KaktoR]

On the latest version of DSG, I used this:

xtool:d1:mue5,k0xB2407C45EA7C528738A94C0A25EA8F419DE4377628EB30C0AE6A80DD9A9F3EF0,kraken:core_2.9.5+srep_new:392+LOLZ_FAST

Game files are the early access version with no extra DLC, 27.5 GB to 24 GB. It's the same improper result as before. Do I need to configure something else in DS?

I have not tested much, but you could rip JP/EN language and 720p/1080p/2160p movies aswell to get a bit better ratio.

I simply have no time atm to test deeper.

Edit: Sorry I used wrong command line syntax. I just realized this now lol.

Use this

xtool:d1:mue5,k0xB2407C45EA7C528738A94C0A25EA8F419DE4377628EB30C0AE6A80DD9A9F3EF0:mmermaid:mkraken:core_2.9.5

What shady encryption is "LEGO Harry Potter 2024 Collection" using actually?

[Masquerade]

^^
Not encrypted, but lzham. File table is encrypted though. Spiritovod shared a bms script on cs (ue4 keys topic) that simply extracts data - great for data mining. Reimport doesn't work due to the nature of the lzham used. FitGirl was kind enough to give me a little bit of info about it.

[KaktoR]

Thanks. Time to delete this then.

Selected ARC/DS method for Data1a-01.bin was: xtool:c32mb:munity,lz4hc,l12+srep_new:393b+lolz:dtb1:d50:mtt1:mt16:mc1023

Overall input size: 3.71 GB
Overall output size: 2.59 GB (Ratio 69.86%)

You can maybe get a bit better results with different "munity" methods.

You can take a lot of size off by converting the banks to ogg audio and using oggre and a hdiff patch.

[KaktoR]

You can save even more space by using an actual codec for unity plugin and the correct lz4 library.



Tick verbose mode and set up unity plugin without any level settings. This way you can see what level you should use. Nowadays unity bundle assets using lz4hc with level 12 mostly.
