How do I do that. If you mean Manage > Delete and update it just asks to update again.

Never mind that’s because I had the dlc too. But it closes the app when I start the software

You need to also disable the required version in devmenu. That should bring you to 1.0 which this guide works with.
 
I personally don't, and i've pretty much given up working on this, but just google RSDK decrypter, that'll get you started
I found a great Sonic Mania Plus rsdk leaked on Google. I would need to find it again but if you want me to link it I can.
 
This doesn't seem to work properly for mods that change core mechanics of the game, for example the modern Sonic boost mod. The sprites, music, sfx etc works but the boost doesn't. Also tried installing a homing attack mod and that didn't work either.
 
today i tried to use the amy mania mod made by codenamegamma but it would only change the spritesets, not the moveset, even includind the .dll inside the repack
 
I just wanted to know how do you run a preexisting mod with add-ons? For example I have the Modern Sonic mod but I want him to have his boost and homing attack ability which are dll files. how do I go about applying them on the Switch? Here is the video of what I am talking about:


I posted the same message @raine_em thread since it was easier using his method of using Sonic mods.

Did you do anything special to get it loading? That's the one mod I want to get working on Switch, but I can't seem to get any Mania Plus mod loading at all - the game just starts normally.
 
Hey guys! So recently I figured out how to run mods from PC for Sonic Mania on Switch! It's a quite simple process.
  • Step 1.
Download any mod for Sonic mania, it doesn't matter, as long as it doesn't replace any .exe files or anything of that sort. (I don't believe a mod currently exists along those lines, so you should be good.)
  • Step 2.
Next, go to your Sonic Mania folder, typically installed to
Code:
 C:\Program Files (x86)\Steam\steamapps\common\Sonic Mania
if installed via steam.
Or, if you dumped mania, the same file should be in romfs.
Now, there is one file in this directory that you actually care about, and this file is "Data.rsdk" this file contains all data information for Sonic Mania. Copy that to a safe place (i.e your desktop)
  • Step 3
Next, go and download RsdkPack.exe (included as an attachment). Place this in the same folder as Data.rsdk. Next, open a windows terminal by pressing shift and right clicking and picking "Open powershell window here"
Once you have this window opened run this command.
Code:
 ./RsdkPack.exe Data.rsdk Path/to/your/folder/with/Data
Make sure that you make the path have one more directory to it. So say this is your directory structure: C:/Users/Bob/Desktop/RsdkPack/, add Data to the end, making this: C:/Users/Bob/Desktop/RsdkPack/Data/
  • Step 4
Now, copy all the files inside of your Data folder from your mod into the Data folder inside of the Data folder. (Confusing, i know.)
Now you are ready to compile. Now run this command.
Code:
 ./RsdkPack.exe Path/to/your/folder/with/Data Data.rsdk
  • Step 5
Now you are ready for LayerFS. If you haven't set up LayerFS, I won't teach you here, but there's plenty of other tutorials on GBATemp. Now, create a folder inside of Atmosphere/Titles/ named 01009AA000FAA000 and then create a folder called "romfs". Copy the file Data.rsdk (if the tool worked, just copy the same file you started with into the romfs folder.)
  • Step 6
Boot into Hekate with LayerFS and enjoy!
Quick question, I have a card of sonic mania for the switch but can't put it in my computer (There isn't a slot.) Do I just have to buy a new computer just to actually mod it or is there some other way to dump it into my pc?
