RTChanger is a homebrew application for the Nintendo 3DS system. RTChanger allows you to change the Raw RTC of your system. This is the only legally distributable open sourced lightweight Raw RTC changer. Changing the Raw RTC allows you to bypass most timegates in games.
There are many applications in different games as some games have more than one time gate. Let's take Pokemon Sun and Moon for an example. You want to train your Pokemon in Poke Pelago. That can take two days or more. Then you want to grow berries which can take days. You also want to do the daily lottery in Festival Plaza, too. Imagine with a new homebrew application, you no longer have to wait. That is now a reality, and RTChanger can manually change your time ahead by any value you want. Almost every timegate in 3DS games will be gone and you'll be able to rapidly train your Pokemon, grow thousands of berries within an hour, and get tons of stuff by the lottery.
Note from developer:
Please note that there are some timegates which RTChanger will not be capable of bypassing. Some timegates are server based, meaning the server keeps the time on their end, and RTChanger cannot bypass these as it's client-side only and there is no possibility of server-based timegate bypassing.
Here's a 3DBrew article on it, which is an extremely reputable source on this.
As you may have seen above in the 3DBrew link, your system has a special hidden clock inside that continues to move forward just like the regular clock and cannot be changed outside of normal circumstances. Upon booting, many games check for differences in the RTC (Your normal system clock) and Raw RTC. Games can detect whether you changed your system clock. However, changing the Raw RTC prevents the games from detecting that if done properly.
As a note, some people call it the Raw RTC, RTC, or hardware clock, but all of these are the same thing (except Nintendo refers to the System Clock which you can set as the RTC).
Installation
Requirements
This will be a CIA and 3DSX file and requires Custom Firmware and Boot9Strap.
- CIA - Installed with FBI.
- 3DSX - Requires Luma3DS as it needs Rosalina to patch the Service Manager (SM) module. Use it with an entrypoint (recommend HBLauncher Loader) or Rosalina.
Note: You must patch Service Manager to use the 3DSX version. This means that Arm9LoaderHax users must use the CIA version.
Before installing
While you are highly unlikely to get any sort of ban, please be aware that there have been ban waves before. Quoting Plailect from his guide (if you have installed CFW recently you should already have this done):
There have been reports of a wave of bans being handed out to CFW users by Nintendo. To protect yourself, please do the following steps before starting this guide.
- Go to System Settings> Internet Settings> SpotPass> Sending of System Information.
- Disable the Sending of System Information option.
- Exit the System Settings.
- Go to your Friend’s List (the Face Icon in the top row of your Home Menu).
- If you receive an error and are kicked out of the menu, the Friend’s List setting is already disabled.
- Go to the Friend’s List settings> Friend Notification Settings> Show friends what you’re playing.
- Disable the Show friends what you’re playing option.
- Exit your Friend’s List.

Installing
Open Rosalina press L+Down+Select, go to Process patches menu, and select Patch SM for service checks. You cannot use the 3DSX version of RTChanger without doing this first. The CIA version doesn't require this, however. Unfortunately, the patch to SM is not permanent, meaning you must patch it every time you wish to use RTChanger.
While you can use any entrypoint you like, here is the release page for the HBLauncher_Loader.CIA, which will allow you to access userland to boot up the 3DSX if you don't have access to any other entrypoint.
Alternatively, you can also use Rosalina with RTChanger. This only requires the boot.3dsx for the Homebrew Launcher 2.0 by fincs. Open Download Play on the Home Menu, then open Rosalina press L+Down+Select and patch SM if you haven't already by going to Process patches menu and selecting Patch SM for service checks. After that, go to Miscellaneous options... and select Switch the hb. title to the current app. Do not attempt to take over any title except for Download Play. RTChanger will crash and any bug reports will be closed if the user did not use Download Play.
If the patch succeeds, press B to exit Rosalina and exit Download Play by pressing the Home Menu button and closing it. Open Download Play again and you should be in the Homebrew Menu, and you can open the application provided you patched Service Manager.

FAQ
Q. Wasn't it already possible to change the Raw RTC? Why was this developed?
Config, a SDK devkit tool which allows you to change your Raw RTC as well exists too. This tool however has been leaked on the internet far and wide. Due to being an official devkit tool, it was not intended to be leaked and was only for PANDA and SNAKE units (3DS and New 3DS developer consoles). As this is officially created by Nintendo itself, it is copyrighted and distribution of it can lead to DMCA takedown requests.
As the Raw RTC was a value stored in the MCU, very few developers knew how to work around it. Sono, otherwise known as MarcusD, was one of these developers. There was little interest in dealing with a program which could do this, and as a new and aspiring developer, RTChanger is especially created considering reddit's /r/3DShacks community didn't have any way to change the Raw RTC, even with Boot9Strap! The only way to change it before now was to get a hold of Config.
Q. Will there be a GodMode9 script?
Author have reached out to d0k3, however it is his decision as to whether he wishes to implement RTC scripting on GodMode9.
Q. This involves the MCU. Is this safe?
Yes. What you may have heard was that changing the color of the LED can brick the MCU, but that was not true as the brick yellows8 got was a NAND brick.
Both the 3DSX and CIA versions has been fully tested on the author's own 3DS.
Q. Does this affect my regular system time?
Sadly, yes.
Q: Is this legally redistributable?
Yes! Feel free to share it to friends, but it is recommended that you send them to the GitHub first.
Q. I would like to build this. What folder should I build?
Don't build the RTChanger-CIA folder.
Q. Will there be any updates to this?
Unless a critical bug arises, there's really nothing else to be done with this application in particular.
