Introduction of the Remaster Doubt

When we first saw the remaster of The Elder Scrolls IV: Oblivion, we must have wondered: how much of it had actually been remade compared to the original? Recently, an editor at PC Gamer ran an experiment.

Core Technical Structure of the Remaster

According to the editor, the original 2006 game is essentially wrapped inside layers of Unreal Engine 5 shell. If you dig into the remaster’s files, you will find nearly all the original‑game files retain exactly the same structure they had back then. (Figure 1 is the original version, Figure 2 is the remaster)

Comparison of Original and Remastered Game Files

As we can see, most of the content is still present. Some things have been removed — for example, the original Oblivion .exe file is no longer in the root directory, and content from the original launcher is gone, while the .ini files remain in their original locations. What about the music, texture and shader folders? They are still there. What about the original game’s .esm, .esp and .bsa files? Completely untouched.

The editor stated he even swapped the main Oblivion.esm file between the original game and the remaster, and both ran perfectly as if nothing had changed. This may explain why so many mods flooded into the community shortly after the official launch of the The Elder Scrolls IV remaster. Because much of the game’s code structure is identical to that of the original.
