+Looking for an excuse to play Undertale again but don't have a Switch? I might have something for you!
+
+The (probably) first mod that is not just another string/texture swap. Made with my [UndertaleModTool](https://github.com/krzys-h/UndertaleModTool).
+
+It's **Undertale, But Every Time A Song Plays Its A Random Remix From YouTube Instead!** (or MixMod for short)
+
+And it does exactly that. Every time a song plays, it searches YouTube for "[song name] undertale remix" and plays a random result from the top N (where N depends on my estimation of songs popularity). Don't like the remix it selected? Just hit the spacebar to choose another random one!
+
+**Installation instructions**:
+1. Make sure you are on Undertale version >= 1.08 (older ones are not supported by UndertaleModTool because of bytecode changes) on Windows (because I didn't manage to figure out how to access GMS surfaces from extensions so I have to pass the whole DirectX context and draw manually - seriously, there is like no documentation on extensions at all)
+2. Download [UndertaleModTool](https://github.com/krzys-h/UndertaleModTool/releases) (the mod script is bundled with the download because I'm too lazy to create a github repo for one file) and [GMWebExtension](https://github.com/krzys-h/GMWebExtension/releases) (the libs only zip file)
+3. Make sure you backed up your Undertale installation
+4. Open UndertaleModTool, load the data.win file from the Undertale directory
+5. Select Scripts > Run builtin script > MixMod
+6. Select Scripts > Run builtin script > BorderEnabler - this is optional, but gives some additional space on the screen for me to put the video player somewhere
+7. Save the data.win file
+8. Extract all files from the GMWebExtension zip into the Undertale directory
+9. Run the game and hope you did everything right and it doesn't crash
+
+I did like 4 quick playthroughs with this and it works most of the time. **Known issues**:
+* Sometimes the wrong song plays. There is not much that can be done about it, it's just a YouTube search over all. If this happens, just make it choose another one by pressing spacebar.
+* Some videos don't want to play. This is because official Chromium Embedded Framework binaries are distributed without h264 support for licensing reasons. It is possible to make it work if I build it from sources, but the sources themselves are like 12 GB and I need to leave the build over night because it takes so long and uses 100% of my CPU. I did it like twice already and still didn't manage to get a working version :> If this happens, just hit the spacebar again for now
+* Almost every time Undertale tries to close on its own, it ends up crashing instead. Not a huge issue as you are restarting the game anyway ;) No idea why this happens, probably something is wrong with deinitialization order
+* The end credits song is normally split into several files, making it hard to play a whole song instead. You will notice the video reloading during room transitions, but it should resume seamlessly.
+* When Sans starts/stops the music really quick during his battle, the video doesn't even have enough time to load properly
