2018 - RE4UHD Toolset by Son of Persia - UPDATED

Hi all, very new here so please forgive me if this should be in a new thread, however I thought this was an acceptable thread given a few others seem to have the same issue as me.
In short, I am having trouble applying the toolset to my files without causing the game to hang and seemingly crash (the game’s memory usage per Task Manager stops dead) when entering the area corresponding to the `r101.udas.lfs`file I am editing.

This includes simply taking the `r101.udas.lfs` (and renaming the original to ensure it does not get loading by default e.g. rename to `r101.udas.lfs.bak`), extracting via the `LFS Extractor`, unpacking the produced `r101.udas` file via `RE4UHD_UDAS_Tool` and then simply repacking again (literally running extract and repack in sequence) via `RE4UHD_UDAS_Tool` and copying the rebuilt `r101.udas` file back to the folder that contained the original `r101.udas.lfs` file.

I am testing the editing of the udas file by starting a new game, proceeding through the first area as per normal, and then upon press E/A to enter the r101 area/Village proper, the game shows the door transition screen affect, but then freezes on the frame before the proper `loading` screen appears, e.g. it simply hangs forever on the zoom effect. I should stress I have not attempted this in other areas, but given I wish to modify the `r101.udas` file at some stage, seems critical to get the most basic case working.

OS is Win7 (I know ...), and the game is the latest Steam version. The toolset I am using is freshly downloaded from the current link on Page 1, however I do have a few older versions of the Toolset that all produce the same results.

For completeness I am still hitting the issue even after running a `Verify Integrity of Game Files` via Steam, and following the same procedure outline previously *without* applying the 4GB patch, nor installing the `UltimateTrainerCompanionByRaz0r`, nor using a v1.0.6 exe (am running the default Steam exe so I believe v1.0.10), so as clean installation as possible (I did try previously with all of these installed with the same hanging/crashing outcome).

For some firmer details, here is the size of the `r101.udas` files before and after extracting/repacking (using the `dir` command via `cmd`):
Before: 10,049,280 Bytes
After: 10,028,704 Bytes

And the MD5 checksum via the `Certutil` tool (e.g. `CertUtil -hashfile <file> MD5):
Before: b4 f2 79 4e c9 6c f7 cd e6 b3 65 79 b6 c0 bf aa
After: ed 97 94 2f a4 ef c6 3c a1 78 eb 38 46 94 4c 8e

Without access to the source code and knowing what the expected udas file structure or MD5 is meant to be, I am not sure what is next - if I have left anything unclear please let me know, I should state that the clean installation plays normally and I can access the Village proper without hanging.

Hey - link to the UDAS tool (not tied to a proper account as I am doing this in a rush, so yell out ASAP if there is issues with the link): www.mediafire.com/file/oeq6ak6ctdigqsw/RE4UHD_UDAS_Tool.exe/file

For completeness, I am using the tools downloaded from the link on Page 1, so: drive.google.com/file/d/1FJPzl2O3Sg00qEJMGBkxUZAtZ7ZTYRdm/view?usp=sharing

Are the toolsets versioned tagged in someway I am not aware of (beyond the usual `-?` or `-h/-Help` cli args)? I have several existing versions of the toolset (all cause the same issue/produce the same repacked UDAS file), however I cannot strongly say when I obtained them which would make diagnosing when the issue was introduced harder on your/SoP's end.

Hey,

Link for the original UDAS (eg simply run through the LFS Extractor via the RUN.bat script): www.mediafire.com/file/xy4assd5hzhn0mz/r101.udas.orig/file

Also, link for my 'repacked' UDAS (eg unpack and repack via the appropriate .bat scripts with the UDAS tool): www.mediafire.com/file/x39mt41yfj2tbzx/r101.udas.repack/file

In addition, I went ahead and was curious if anything at the binary level of the two files was so out of place that it was noticeable to someone like me who isn't as familiar with the UDAS file structure - links below are screenshots of side by side comparisons of the two files in HxD (been a while since I played with binary data, so forgive me if my terms are wrong).

In the pics, left is the original UDAS and the right is my repacked UDAS.

First link is the start of the files, where the header is clearly reversed as mentioned by someone else previously, however you can also see there is nearly 20 Bytes of missing (I assume) padding before the start of data e.g in the original can see '0x25' value at the 0x420 position whereas in my 'repack' version it is at the 0x400 position.

Second link was me curious to see how much data had been truncated off the end given the file size difference, and you can see from the final offset on the right vs the left just how much has been snipped off. Interestingly, it seems that only those 20 Bytes I mentioned from before are the only missing Bytes (though this doesn't mean a heap of other Bytes have been flipped or written incorrectly, etc) given the start of the 'D8 3F 4A' Bytes (position 0x99028D - 0x99028E on the left and 0x99026D - 0x99026E on the right). But there is clearly something severe going on, as the right ends at offset 0x990690 while the left ends at offset 0x9956F0.

The above is probably overkill, but beyond sharing the files and without access to source code I am not sure what else I can do to help out - most of my dev experience lately is more in the Java/Python space and has been quite a while since I did anything this low level (and even then that was Embedded C development).

Original r101.idas.lfs -> www.mediafire.com/file/500i4t0r2y20qzd/r101.udas.lfs/file

I freshly downloaded/installed RE4HD from Steam the other day, so whatever the latest version is on Steam is what I have, which I had thought was v1.0.10 (as I had thought that was the latest version and hence the version on Steam), though as stupid as this sounds I am having a bit of trouble confirming the version on my disk - Steam update page mentions v1.0.6 as the last update, and via the properties window on the exe it is 'apparently' `File Version: 1.0.0.0` ...

You know, as a preemptive measure you could simply get the RE4HD project UDAS files and work with those. THose should be the baseline for all stage mods anyways as ALbert has made some changes to the pack files and tweaks to some of the rooms.

So you have:

the same file as I do
the same tool as I do
but your tool changes the file while mine doesn't.

The only thing I can imagine now is that it could be the LFS tool. Please upload all the files that are in the LFS folder in ZIP file. I will compare all the files to the ones I have on my machine. If everything is identical again, then we are in for a big mystery.
