OBSE "clears" Oblivion 4gb flag? : IV

» Tue May 08, 2012 11:02 am

I had to open up to a question about this, because I can't find the OBSE thread.

I bought the Oblivion GOTY deluxe edition from steam. It works nicely with OBSE.
However, since I applied the 4gb enabler (or LAA flag) to Oblivion.exe the game does not launch.

Everytime I used to revert back to the original, but it doesn't launch.
I found out that everytime Oblivion does not lauch with OBSE, re-applying the 4gb flag makes it run again.

I looked into the OBSE Loader log file, it has this:

clearing large-address-aware flag (flags offset = 0000011E checksum offset = 00000160)recorrecting exe checksum (00793BFD -> 00793BDD)crc = A2408F04You are trying to use a Steam version of Oblivion. Steam users should launch the game through Steam, not by running obse_loader.exe. If OBSE fails to load, go to Steam > Settings > In Game and check the box marked "Enable Steam community in game". Please see the instructions in obse_readme.txt for more information.

The funny thing is that I can change the executable with the 4gb flag and the steam version works fine.
However, when I launch the game with OBSE loader it issues a warning telling me that I should use the Steam Oblivion launcher instead. :ermm:

Wait, what?

does it have anything to do with "legitimizing" the use of OBSE in the steam version? I know that Oblivion (possibly Morrowind too) doesn't have DRM issues. Skyrim on the other hand needs that fancy memory injector since patch 1.1.
I also say this because I also used the Oblivion DVD version for years and never had any problem. After using the Oblivion DVD executable, patched with the latest Official Version, however, the same thing happens:

tl/dr;

OBSE 20.6 does work all the time with original versions. I am only trying to figure out what it is doing with the 4gb version that I modify for myself - on purpose. The Obse launcher refuses to work with that on occasion. :mellow:

Is there a way to enable 4gb flag and still make OBSE loader run the executable?

It isn't really turning off the flag btw. It's only temporary so it can do the CRC check.

Thank you Psymon.

I figured that it should not, since I had tested it since so long ago and it always worked.
What I am intrigued about is that Steam version sometimes does not lauch with these steps:

1. Patch Oblivion.exe with this tool - http://www.ntcore.com/4gb_patch.php
2. Launch Oblivion from Wrye Bash, with OBSE 20.6 installed and enabled.

First time, the Oblivion launcher shows upa, I click play and the game works with OBSE enabled.
Then after that, tried to lauch again and nothing happens. If I apply 4gb patch it works again. That is odd, no?

Not if Steam is silently replacing the exe file in the background. There's precedent for it doing so with Skyrim and the stealth DRM patch.

Aha! Thank you Arthmoor. :foodndrink:

It must be the case; only the Steam version some times refuses to launch.
