Hello folks, I know it's been a while and I'm itching to learn how RE4UHD's modding works. It seems somewhat different from what I remember, especially with Son of Persia's awesome tools. However, I've hit a bit of a snag. I'm trying to load a repacked UDAS file. I originally thought I modified the files incorrectly, but upon repacking a freshly unpacked file, the game still refuses to load it. Basically, I get a hang and a "not responding" issue. The game doesn't outright close.
For reference, I am attempting to load Stage 1 of the Mercenaries (the town, r400) Here is what my process looks like: Unpack r400.udas.lfs (which becomes r400.udas) Unpack r400.udas (which becomes a folder with r400 and r400.idx) Immediately repack r400 into r400.udas Remove r400.udas.lfs from St4 folder in the installation folder (have a backup, don't worry  ) Place r400.udas in St4 folder Boot game and attempt to load Village in Mercenaries w/ Leon I've attempted this with both the base install and the 4GB patch, as well as attemtping to use the 1.0.6 .exe. So, is there an issue with my process?
As a note, simply extracting the lfs file and placing the resulting udas file (with the lfs removed) properly boots the game. I think I am missing a single step somewhere. Hopefully I'm not being stupid and just missing a tutorial somewhere.

I have reviewed all the steps you have taken and I can say that you have done nothing wrong. I suggest that you look at the difference in hex editor after the Udas is repacked (compared with the file before extraction) If you see some differences there than you know something isn’t right…
May I ask where you downloaded the tools from? Was it from the recent release I posted or from the original download from Son of Persia ?
Cheers

Hi Mr. Curious! I did notice there is a difference when viewed under a hex editor. It is definitely possible that I have outdated tools, so I will grab the tools from your post and give that a whirl. I will post here after testing.

EDIT: For reference, here is an image of the two files, shown from the header. Top is the original UDAS before repacking, and bottom is the repacked one.

Weird. Looks like their Endian order is different. Can you down load the tools from my thread and try them out and post results here ?
Cheers

Oh it looks like you might have already grabbed the one I released. I am not at home (on vacation) so I can’t test the tools. I hope there is no issue with them being compressed in 7.zip. Seems odd that both udas tools would do the same thing.

You wouldn't happen to have an older version of the UDAS tool somewhere zipped differently, would you?

I do but I won’t have access to that file until I get back from vacation. Is there a way you can test it on another machine ? It’s strange that BOTH won’t work for you.
Cheers

So I figured out what I believe to be a working solution: As Mr. Curious pointed out, the endian order on the header was reversed. I scrolled through the rest of the file and noticed that it was *just* the header that was reversed. I took the highlighted segment from the original UDAS and pasted it over top of the repackaged UDAS.
However, this was not enough. It didn't load in this case for me. But I also noticed something else...
At the same offset points of both files, the data of the repackaged data (right) was higher up. It looks like some data was missing. So I just added 32 bytes of empty data (2 rows shown below consisting entirely of 00s) The finalized file (on the right) works properly after making both of these changes! In addition, I also tested this by modifying an ITA file and then repacking. This worked properly. I'll need to do more testing to verify but this method seems to work for now.

ok so to test this I downloaded the current 2018 Son of Persia Tools here
TO start testing I took the original LFS version, removed it with the BMS script and then unpacked the UDAS with the downloaded tools. I then looked in HEX. Repacked and then look at it again in HEX. Nothing changes. File maintains same data. I compared this with an unaltered version (a copy of the udas that hadn't been unpacked or repacked), and compared it to the first one above. The result was that there were no differences in files which leads me to conclude that the UDAS tool included in the current download for the Son of Persia toolset is working perfectly. I don't know how this works. Perhaps your HEX viewer is off, maybe one of your windows components is off. I don't know. Best of Luck.

Its seems that another user hexmoddin has had the same issue. I can not explain why this is happening, but perhaps you could both compare scenarios. Perhaps it is an OS issue? Or Java, or Runtime Environment issue? I don't know why the same tool on my machine, tested with the same files, would produce different results.

Sorry to necro an old thread, but I think its important here to understand that if we unpack 1.10 version UDAS files with SoP something goes wrong with the files. Its important to base your mods off of the 1.0.6 version of the game files. kTeo should have a link to the 1.06 game files.

I do. i made a personal backup for all .udas files from 1.06, you can download it HERE
