Setup
Head to the Lime3DS Releases page and download the latest .APK onto your Android device: https://github.com/Lime3DS/Lime3DS/releases
Install the APK and then open Lime3DS.
Click Get Started.
Grant permission for Notifications. Allow on the popup from Android. Click Next.
Grant permission for Microphone. Can click “while using the app” on the popup from Android. Click Next.
Grant permission for Camera. Can click “while using the app” on the popup from Android. Click Next.
Now we need to select our User Folder, and that’s where Lime3DS will save all of your data.
Click Select, and it should take you to your Internal Storage. Select Create New Folder at the top, and name it Lime3DS. Then select Use This Folder at the bottom. Then OK. Click Next.
Now we need to tell Lime3DS where our 3DS games are located. If you don’t have any ROMs, use the video below as reference.
Click Add Games and navigate to the folder that has your 3DS games in it. Click Next. Then click Continue.
Settings
Now you’re at the home screen of Lime3DS and you should see all of your games populating, but before we open and run anything, let’s make some setting changes.
Click the three dots on the top left for Options. Then click Settings.
Configure Controls
Head to Gamepad and then map the controls of your device to the inputs on-screen for a 3DS. Back out a screen when done.
Configure Graphics
Now head into Graphics, and this will be something you’ll need to test on your end, but in a lot of cases, you’ll want to change Graphics API to Vulkan.
Then, in either scenario, OpenGLES or Vulkan, you’ll want to test turning on Enable asynchronous shader compilation.
For Internal Resolution, this will be dependent on the power of your device. You can try upscaling if you have a decently powered device. Back out to Options when done.
Installing updates/DLC
If you head to Install CIA file, you can install updates and DLC files. These come in the .CIA format. If you have them, this is where you’d install them. Back out to the Home Screen.
Removing on-screen touch controls
From the Home Screen, if you select a game, you’ll boot into it. Let’s jump into one now.
The first thing you’ll notice is there’s on-screen touch controls, and if you’re using a Handheld device, we don’t need that.
Access the in-game Lime3DS menu by pushing the Back button on your Handheld device (if it has one), or swipe up and click the Back arrow and you should see the panel pull out from the left side.
Head to Overlay Options, and uncheck Show Overlay.
Show FPS
From the in-game menu, head to Overlay Options, and check Show FPS.
Change screen layout
From the in-game menu, head to Landscape Screen Layout and change to any of the other options available. You can also choose Swap Screens from this menu.
Cheats
For Cheats in Lime3DS, you can access the Cheats menu using the in-game menu, then Cheats or from the Home Screen of Lime3DS by pushing and holding on a game with your finger.
To find Cheats, head to this Github: https://github.com/JourneyOver/CTRPF-AR-CHEAT-CODES.
At the top, head into the Cheats folder, and you should now see a whole list of games.
Find the Game that you want to add Cheats for, and you have to make sure the Region and Version matches the game you have.
Click into the Game folder, and you should see a .TXT file with a long string of numbers. Click into that and you’ll now see a whole bunch of cheats.
Click the Download button on the top right labelled “Download raw file” and you should download that .TXT file.
Move that file into your Lime3DS folder, Cheats folder. If you followed this guide, it will be on your Internal Storage, Lime3DS, Cheats.
Open Lime3DS, and find the Game you added Cheats for, then push and hold on the game with your finger.
If you grabbed the right .TXT file that matches your game’s region and version, you should see your cheats in a list, and you can enable or disable them.
Alternatively, if you’re in-game, you can open the Lime3DS in-game menu, select Cheats, and enable or disable them on the fly.
60FPS
For 60FPS Cheats in Lime3DS, you enable them the same way you enable Cheats above.
To find 60FPS Cheats, head to this GBATemp post: https://gbatemp.net/threads/60-fps-patches-cheat-codes-releases-and-discussion.550527/.
Find the Game you want to add 60FPS Cheats for, and if you click it, you’ll see codes depending on the version of the game.
Then, in Lime3DS, you want to push and hold on a game from the Home Screen with your finger, and you should see the Cheats menu and a Plus icon bottom right to add Cheats.
Give the code a name, so 60FPS, and then in the Code box, you want to copy/paste or enter the 60FPS cheat code that matches your game version.
Once you do, you should see your 60FPS cheat in the list, and you can now enable or disable it.
Alternatively, if you’re in-game, you can open the Lime3DS in-game menu, select Cheats, and enable or disable it on the fly.
HD Texture Packs
To install HD Texture Packs in Lime3DS, there’s a few steps.
The first, as of right now, there isn’t a good consolidated list of HD Texture Packs in one place, so you’ll need to find them separately on a per-game basis.
Once you do, open Lime3DS, head to Options, Graphics and scroll all the way down and enable Custom Textures. It’s also handy because it tells us exactly where to put those HD Texture Packs right here.
Then, just boot up any game so it can populate those folders for us. Boot up a game, exit the game.
Now, you can put your HD Texture Packs inside of the Lime3DS, load, textures folder (with whichever folder you put in here being the TitleID of the game).
Example – Ocarina of Time 3D HD Texture Pack
Let’s use an example, and I’m going to use Henriko Magnifico‘s awesome Ocarina of Time 3D 4K texture pack seen here: https://www.henrikomagnifico.com/texture-packs (you have to scroll through the Patreon to get to the free posts and there will be a Download link in the post).
The file you get after downloading is either Zelda OoT 3D 4K 1.9.0c (4K).zip or Zelda OoT 3D 4K 1.9.0c (1080p).zip, depending on the resolution you want. Extract whichever zip file you downloaded. If you downloaded this on to your device, you can use Solid Explorer File Manager as a file manager and to extract.
Now head inside to the user folder, then load, textures, and if you’re using the NTSC version of the game, it would be the one that ends in 500 > 0004000000033500.
You want to copy that folder onto your device, and put it into your Internal Storage, Lime3DS, load, textures folder.
Boot up your game and enjoy the awesome HD Textures!
