I intend to go through the Community Patches and all my own mods to convert all files to lowercase, and due to the monotony of such a task, I'm thinking of writing a program to do it. I only own the games on Windows, so it would be help to have someone who owns them on Mac, Linux, and/or iOS and is comfortable with installing mods on any of those systems to be able to test it.
Specifically, I'd like to determine to what extent it's necessary to hex edit model files that reference the names of other files (e.g. textures). If I recall correctly, @A Future Pilot reported that files packaged in RIMs and MODs also have to be renamed, so there may be a similar issue here.
Note that this issue does not affect the Android version. Even though the Android operating system is Unix-based, it is designed to be case insensitive so as to behave with file systems that are not case sensitive. It'd be nice to receive confirmation on that, though.
