Do NOT edit oblivion_default.ini. It is a template of Oblivion.ini generation.(at worst, you may reinstall whole game just because of this file) Oblivion.ini should be at \(Username)\(My Documents)\My Games\Oblivion\.

TES4Gecko reads certain registry entry that was generated at installation back then. Said entry is not 'generated' at Windows 10(64bit) I think, so you need to manually add it. By the way, have you read this? https://forum.nexusmods.com/index.php?showtopic=30305/&do=findComment&comment=121251849 And, If I'd make a shortcut or batch file, I'll make one in the place where TES4Gecko is, then edit it. (I'm lazy, so I just let Java installer make association with .jar)

It's not that hard to make one. But you may need to do many times of drag-and-drop if there are many many hairs(and eyes, maybe) to add. - (Make a plugin that adds 'extra' hairstyles to races you want) 1. (In CS) If a hairstyle is not playable, check 'playable' at hair list(Character->Hair). Do not close the list yet. 2. Open race window(Character->Race), go to 'Body Data' tab. Choose any race you want. 3. Click any hair you want. Drag it on the Body data->Hair Styles list. This will add new hair style to a race. 4. Rinse and repeat.

Does GOG Oblivion support cloud save? (I don't use launcher, so I don't know... but if so, you can disable it at 'Manage installation'->'Configure'->'Features')

Just stopped by: If you read about Elder Scrolls lore, you may find devs construct Nirn's pantheon(s) and religion(s) based on 'how real world polytheistic religions and pantheons work(and transform)'. This fictional world have gods who meddle with mortals in various ways, and sometimes(though rare) appear before them in flesh. Also they have regional, racial variants of those gods as well as local minor gods.

I've heard GOG version is, don't know about steam version(dispite of having one in my library).

Maybe through WINE? I don't know about that, though.... But I think you can patch files in your PC, then transfer them to Steam Deck?

Currently known popular body mods(HGEC/RM/RF) have underware option(Robert's male body has several...). You wouldn't find any 'non-nude skin texture' because underware is clothing meshes on base body. **Oh, and don't forget to get 'Seamless' series by junkacc11. It will reduce seams(almost invisible).

I've seen blank EGT for Head06(from Head06 resource), but I don't think I've found blank vanilla head and body EGT files. (You may need them if you want to 'disable' facegen color slider without turning off Facegen texturing in Oblivion.ini) Has anyone made and shared them ever?

'The title is the question' Because why not. Weeks ago my desktop computer died after suffering sudden freezing for several days, so I had to buy new parts and build one. I reinstalled the game this morning, but this time I installed one from GOG. Since I also have the game in my steam library, I wondered if I can install both at the same computer. Of course, both copies will likely share documents\My Games\Oblivion if it can be done(would thay share registry as well?). I don't think I'd try that, but maybe....

And, if you got the game(GOTY) from Steam or GOG, you won't need patches.

Hmph.... then backup your music folder first, delete all metadata from those mp3 files with any means and check if the game would play them... (I wonder if bitrate also matters. If not, I'd try to replace all the vanilla tracks from OST I bought from steam)

The music files are in \(Whateverfolder)\Oblivion\Data\Music\ as normal mp3 files. If the music is truly replaced, all you can do is reinstall the game unless you made backup of vanilla data files. (Well, if you're on steam, you don't need to reinstall the whole game...)

To convert armor, you may need 3D modelling tool, such as blender. And there was a set of tools called 'KGTools' which generates lattices and convert outfits for different body types.
