Preparing SD Card:
1a. Grab the files from here: drive.google.com/file/d/1Bjt_AohKiUHwfo6sHeIpTjrSyhoqaOmR
1b. If you use Ryujinx instead, get the files from here: drive.google.com/file/d/18bZyRP5nB9N8RJp_X4Hu4jcbu_dnKf2K (video doesn't include a guide about the emulator part, so either you have to know what you're doing or just ask for help).
2. Put the atmosphere folder and the switch folder onto the root of your SD card.

Uninstalling v1.0.2:
1. Load the Homebrew Launcher and go to DB Installer.
2. Go to Browse Installed Applications ... Super Mario Bros. 35.
3a. Highlight Version 2 [v131072], and press the (+) button and press Dump to SD Card. Only do this if you do NOT have v1.0.2 of the game backed up, this is important!! MAKE SURE THAT YOU HAVE IT BEFORE UNINSTALLING v1.0.2!!
3b. If you have your update file backed up somewhere, you then can remove v1.0.2 by simply press Delete.
4. Go back to the Nintendo Switch Home menu, and your game should be now v1.0.0.

Installing v1.0.2:
1. Load the Homebrew Launcher and go to NX-Shell.
2. Go to atmosphere\contents, and find Super Mario Bros. 35's 0100277011F1A000 folder.
3a. Rename 0100277011F1A000 to something else (by pressing the (X) button and press Rename) so that you know this is v1.0.0 and that you want to play it again some time.
3b. If you had a 0100277011F1A000 folder before that included custom textures, music and so on (FOR v1.0.2 THAT IS!!!), you can now rename that folder back to 0100277011F1A000.
4. Press the (+) button and load DB Installer.
5. Go to Browse SD card and find your v1.0.2 nsp file you made a backup of.
6. Highlight the v1.0.2 nsp file and press the (A) button.
7. Make sure "Install Target" is set to NAND, "Delete after install" to No and "Turn off screen" to No.
8. Press Start Install and let it do its thing.
9. If done correctly, you have successfully installed v1.0.2 while also preventing your v1.0.0 files to load!
