I have been using Wrye Bash on Oblivion. Not sure what your system is like but I’m on Arch and using a slightly older version of WINE and made a bottle for Oblivion. Just run WB under the bottle. I have the GoG version of Oblivion so not sure if that matters.

“I’m just really happy rn yall” - be careful with that rn command if you’re anywhere near Arch, wouldn’t want all your happy uninstalled! Seriously though, good for you! Welcome to freedom.
