Switch KotOR Modding romFS Dummy Folder with 1.0.3 dialog.tlk
This is a set of files and folders designed to make modding the Switch version of KotOR easier and more accessible to a novice user.
Read to the end before using.
You will need a hackable, or modchipped Switch to use this, and custom firmware must be installed, I use Atmosphere, but anything that supports romFS should be fine. 
This should work just fine with the digital or physical version (when it is released) without issue. I have only tested this on the most up-to-date build at this time, 1.0.3. It may work on 1.0.2 or 1.0.1, but it is not guaranteed, and I'm not concerned with supporting them.
Extract the zip file, and install any mods you want to use, pointing TSLPatcher at the romfs folder containing the dialog.tlk file. For mods that don't use TSLPatcher, copy files as directed, "romfs" is equivalent to the directory on PC containing the executable.
NOTE: You may need to move files that TSLPatcher is expecting to the folder to be able to patch them. You can access them by dumping your game with nxdumptool, using romfs. Make sure you include updates when doing so.
Feel free to comment with what you needed, and what mod it was for, and if there is popular demand, I will add the files to this pack. The easiest way I found, was just to try installing a mod, and then check the log for errors to see what files were missing.
NOTE: Long filenames cause issues with TSLPatcher, this is exacerbated by the length of the filepath for romFS modding. I recommend moving the "romfs" folder to the root of the drive and patching there, moving the folder back afterwards.
Make sure to check your error log, you may manually need to copy .lip files over to override afterwards.
Move textures (.tga, .txi and .tpc) to override/Textures or they won't apply.  NOTE: Aspyr included upscaled textures with this version that are not in other releases of the game. As far as I can tell, they are all in the format the original textures were in, by and large, that means they are in .tpc format, which trumps .tga and .txi files of the same name. If you have issues with a mod's textures not applying, try converting them to .tpc with Xoreos-Tools. You can download my texture reversion mods for K1 and K2 on Switch if you want to see what files are in what format.
At this point, copy the atmosphere folder to the root of your SD card, and you should be done. Please feel free to mention any issues you run into, or workarounds you needed, and I'll update this post.
I tested a run of K1CP with no major issues.
Mods that involve UI likely won't work. Everything is at your own risk, you may end up with a broken save, etc. Worst case scenario, you can uninstall all mods by deleting the `0100854015868000` folder from `/atmosphere/contents/`
Big thanks to JC for helping me pin this all down.

Just a change to the readme regarding potential texture issues.
 

I wondered, why wait a few months for Aspyr to release TSLRCM when you could hack it together in a few days for fun? To that end:
Switch KotOR II Modding romFS Dummy Folder 1.0.1
This is a set of files and folders designed to make modding the Switch version of KotOR II easier and more accessible to a novice user.

You will need a hackable, or modchipped Switch to use this, and custom firmware must be installed, I use Atmosphere, but anything that supports romFS should be fine. If you use something other than Atmosphere you'll have to figure out where it goes, but it should be very similar.
This should work just fine with the digital or physical version (when it is released) without issue. I have only tested this on the most up-to-date build at this time, 1.0.1. I will update this when the next patch is released, and hopefully again when TSLRCM is officially released.
Extract the zip file, and install any mods you want to use, pointing TSLPatcher at the \Localized\English\ folder containing the dialog.tlk file. For mods that don't use TSLPatcher, copy files as directed, "romfs" is equivalent to the directory on PC containing the executable.
NOTE: You may need to move files that TSLPatcher is expecting to the folder to be able to patch them. You can access them by dumping your game with nxdumptool, using romfs. Make sure you include updates when doing so. What I included should be more than sufficient for TSLRCM, however.
NOTE: When you are done, move the override folder to the root of the romfs folder, i.e. the directory with the "swplayer.ini" file.

I tested a run of TSLRCM and Leilukin's Gay Handmaiden mod with great success. I have not tested the Male Exile/Disciple part of that mod, but it should work as well.

Big thanks to JC for a ton of help troubleshooting, and big thanks to Zbyl2 for helping with TSLRCM-related issues.
7-22-2022 Update:
Just a change to the readme regarding potential texture issues.

KotOR Switch Texture Restoration
The Switch port of KotOR included some upscaled textures for much of the game. While some of these look fine, I found some of the armor and character portraits pretty bad to look at. I'm not sure why, but these were not advertised or mentioned, and there is no way to turn them off in game.
This mod restores the original textures for the character portraits, armor textures, while preserving the new UI and button prompts.
Please notify me if anything is broken or you run into issues. I played about an hour with this mod, but it has by no means been exhaustively tested. It should not cause any major or game-breaking issues though.
This is compatible with, but does not require my KotOR Switch Modding Framework, if you wish to use this with other mods that change textures, install this first.
NOTE: Like any other mod for Switch, this requires a hacked or modded Switch with custom firmware. This can probably be adapted to firmwares other than Atmosphere, but I offer no support for them.
Installation is dead simple, extract the "atmosphere" folder to the root of your SD card. If you wish to uninstall:
If this is the only mod you installed: Simply delete the "0100854015868000" folder under atmosphere/contents/
If you installed other mods, it will depend. I would generally recommend just wiping clean for safety, or if you didn't install any other texture mods, you could delete just the "Textures" folder in override.
Big thanks to JC for a ton of help with this mod.

KotOR II Switch Texture Restoration
The Switch port of KotOR II included some upscaled textures for much of the game, just like the first game. 
While some of these look fine, I found some of the armor and character portraits pretty bad to look at. Not as bad as K1, but still annoying at times. I'm not sure why, but these were not advertised or mentioned, and there is no way to turn them off in game.
