Hi, so I tried to extract Rayman Origins' IPK file using the latest version (0.2.5) of this script:
http://aluigi.altervista.org/bms/rayman_origins.bms

But for some reason, QuickBMS fails extracting it, giving me this error:
"Error: the compressed zlib/deflate input is wrong or incomplete (-3)
Info: algorithm 1
offset 0027d92c
input size 0x00000e14 3604
output size 0x00000001 1
result 0xffffffff -1

Error: the uncompressed data (-1) is bigger than the allocated buffer (1)

Last script line before the error or that produced the error:
124 clog NAME OFFSET ZSIZE SIZE"

Ironically, I tried this script out with Rayman Legends' IPK files and it was able to extract the files from it just fine.

Upload the ipk file.
If it's very big (over 500Mb) it's probably better to use the http://aluigi.org/bms/filecutter.bms script with the MEGABYTES variable set to 10.

The "output size" equal to 1 is for sure a problem that must be solved.

Okay, here's the IPK file:

I couldn't get the file-cutter script to work so I had to upload it normally so it's 1.57 GBs.

Script 0.2.6

Thank you! It's working perfectly now.

Okay, so I'd like to bring up the fact that your script works with pretty much every Rayman game with the IPK format now except for one, Rayman Adventures because it uses a newer engine format (which I believe is version 8).
If you can add support for that game, that would be great.

Yes! Thank you so much, now every IPK version is supported, even the Switch version of Legends' IPK files work on this.

Hey, sorry for bumping this old topic, but this is important.

There is a beta demo of Rayman Legends that was released in 2012 on the Wii U eShop and it turns out it also uses a different file structure for the IPK files because it runs on an older engine version so that means that your BMS script doesn't support it. If you need any help, let me know! Thanks!

Okay, so it turns it's actually worse than I thought, your script doesn't support the Wii U version at all, period. I tried using it on all the Wii U demos and the final Wii U build as well, but it gives me the same type of error, so it looks like this affects all Wii U versions of Rayman Legends. Thankfully, Droolie's script that he posted on this thread can extract from the Wii U versions just fine, but if you can fix your script that would be better because it would be better to have one script that extracts from all IPK versions: http://forum.xentax.com/viewtopic.php?f=10&t=10690

I guess I have found a compatibility work-around but the presence of multiple versions and customizations of the format doesn't help in these cases
Script 0.2.9

Wow, I can't thank you enough, I just tested it on both the Wii U retail and beta demo versions and it works perfectly, this script should be compatible with all of the Rayman IPK formats now! You've done a lot of favors for us at the Rayman modding community.

There might be a few other Ubisoft games that use different IPK formats, but I think I'll leave that problem to whoever else wants to post about it.
