How to Install a ROM Patch for Super Mario Bros. Deluxe 'en-US'

Super Mario Bros. Deluxe is an excellent emulator-friendly version of one of Nintendo's most iconic games. While it already offers plenty of fun as-is, some dedicated fans may be looking to take things even further with custom modifications.

One way you can do this is by using a ROM patcher like Dolphin or Citra on your Android device. These applications are specifically designed for managing and editing ROMs (Read-Only Memory) files used in older Nintendo games that were never officially released outside of Japan due to region locking issues during their initial release dates wherein players could only access certain content based because they owned the original cartridge insertible into slot A within hardware capable supporting such features at time when these titles first hit store shelves worldwide!

In this case, we're going to focus on installing a specific patch for Super Mario Bros. Deluxe called 'Super Mario 3D Land Rom Hack.'

Step-by-Step Instructions:

1. Download and install Citra from the Google Play Store or via direct download link if you haven't already.

2. After installation is complete, launch Citromizer (the emulator's built-in ROM manager) within your Android device by tapping on its icon located either in home screen dock area depending upon how much space available left over after installing all necessary apps before proceeding further down guide lines below which will walk through process of finding appropriate rom files to play using citra itself.

3. Once inside Citromizer, navigate to the 'SDcard/Android/OBB' folder on your device's internal storage or SD card depending upon where you chose during initial setup prompts asking about saving location for game data later used by emulators themselves when launching individual titles from main menu afterwards without having to constantly search through entire file system again every single time wanted play something different than usual default options presented first thing after opening app itself.

4. Within the 'OBB' folder, look for a directory called '.com.nintendopc.smbdxp'. If it doesn't exist yet, create one by right-clicking (or long-pressing on some devices) within that particular directory and selecting 'New Folder'.

5. Inside this newly created folder named after our specific game title ('Super Mario 3D Land'), you should see several files including an .ipa or .apk extension depending upon whether your device runs Android OS version lower than Marshmallow (6.x.x), otherwise look out for '.zip' compressed archives instead containing all necessary assets needed to launch gameplay smoothly without any issues whatsoever.

6. Extract the contents of this zip file into a new folder called 'Super Mario 3D Land Rom Hack' within Citromizer's main directory structure mentioned earlier above step three where you'll find various folders like 'sound', 'gfx', etcetera; these contain graphical and audio assets used throughout gameplay experience itself so be very careful not to overwrite any existing files already present there as doing so might corrupt entire setup completely rendering it useless for future use.

7. After extracting all necessary asset files into their respective locations inside newly created folder structure, launch Citra from within Android's app drawer or home screen depending upon how you've configured your device's launcher settings prior to launching this particular application itself...

8. Once inside the emulator main menu, navigate through various options until reaching 'Options' > 'Paths', then select the correct path leading directly towards extracted game rom files stored earlier as per instructions provided above.

9. Finally, restart Citra after making these changes and launch Super Mario 3D Land Rom Hack from within its main menu to enjoy your fully patched experience!

Remember that some ROM patches may not work with all versions of Android or even specific devices due to compatibility issues between different firmware revisions used across various hardware platforms. Always check the patch's description before attempting installation for more information about system requirements and known limitations.

By following these steps carefully, you should now be able to enjoy Super Mario 3D Land Rom Hack on your Android device with ease! Happy gaming!
