## #0 Pokémon X/Y Support
|
||||
|
||||
We are just as happy as everyone else to finally have Pokémon X/Y support after so many years!
|
||||
We didn't include this one in the survey because at the time, we weren't even sure if the long time spent on developing the new audio core code would fix the game.

|
||||
At first, this new HLE code was using patented decoders that Citra legally could not distribute, making it painfully complex for anyone that wanted to test it out.

But with way more effort than anyone expected, we were able to modify the HLE code to use Microsoft's [Media Foundation](https://en.wikipedia.org/wiki/Media_Foundation) framework, which allowed us to ship HLE (fast) audio support for Pokémon X/Y without any patent issues.

## #1 New 3DS Support
|
||||
|
||||
In September, developer [B3N30](https://github.com/b3n30) started deep research into what exactly it would take to fully support N3DS games in Citra.
|
||||
Keep in mind that we wanted to implement **full** support, which involved more than just hacking it on top of what Citra has today.
|
||||
On the hardware level, the N3DS added some additional memory and most importantly, added 2 new CPU cores, one that's dedicated to facial tracking and one that games can run code on.
|
||||
And on the software level, it has a few new N3DS specific services, mostly just to let the game know that it's running on a N3DS.

And on the software level, it has a few new N3DS-specific services, mostly just to let the game know that it's running on a N3DS.
|
||||
|
||||
The challenge with adding N3DS support ended up almost completely within the scheduler, as increasing the emulated memory and CPU count were pretty straightforward.
|
||||
Citra's current implementation is written exclusively to run all 3DS code on one emulated core, something that works great for just about every game out there, as that's how it works on real 3DS hardware too!
|
||||
But N3DS games (and a small number of O3DS games) can intentionally run code on another core, which we don't have any support for at this time in Citra.

||||
But N3DS games (and a small number of Old 3DS games) can run code on another core, which we don't have any support for at this time in Citra.
|
||||
|

After a few months of playing around with the code [B3N30](https://github.com/b3n30) had to take a break; as it was too exhausting trying to reverse engineer how the 3DS schedules across multiple cores and recreate this in Citra at that time.

After a few months of playing around with the code, [B3N30](https://github.com/b3n30) had to take a break, as it was too exhausting trying to reverse-engineer how the 3DS schedules across multiple cores and recreate this in Citra at that time.
|
||||
It's an open secret in the 3DS reverse engineering scene that the 3DS scheduler is devilishly complex.
|
||||
So while we do plan to continue working on this, sometimes you just need to take a break and come back with a fresh perspective.

## #2 Splittable Screens
|
||||
|
||||
Developer [jroweboy](https://github.com/jroweboy) started work on splitting screens to multiple windows in Citra a good while ago, but almost immediately ran into an issue.
|
||||
This task touched many parts of the code that are very core to the emulator and changing them proved to be a little challenging.

This task touched many parts of the code that are very core to the emulator, and changing them proved to be a little challenging.
|
||||
While these technical challenges are easy for the devs to handle, the real challenge was developing a clear and usable UI/UX for the feature.
|
||||
|
||||
Having to create a multiwindow system where it is intuitive enough for users to discover how it works, powerful enough to cover everyone's preferred use cases, while still being simple enough to not cause massive maintenance burden, are very challenging design goals to meet.

|
||||
|
||||
Most developers have a passion for working on complicated core emulator projects.
|
||||
But a good emulator should also be user friendly and easy to use, and that's not something emulator developers usually have much experience in.

||||
We do want splittable screens, but we won't settle with a bad design.

## #3 [Controller Hotplugging Support](https://github.com/citra-emu/citra/pull/4141) by [B3N30](https://github.com/b3n30)
|
||||
|
||||
In response to the initial survey results, both [jroweboy](https://github.com/jroweboy) and [B3N30](https://github.com/b3n30) set out to change the controller handling code in Citra to support [hotplugging](https://en.wikipedia.org/wiki/Hot_swapping).
|
||||
On the surface level, the bare minimum requirement was that one could unplug and replug in a controller and Citra would continue using it.
|
||||
But deep down, Citra needed a little bit of restructuring for this to be possibly implemented.

||||
But deep down, Citra needed a little bit of restructuring for this to possibly be implemented.
|
||||
|
||||
What followed was a full redesign of the controller backend to not only make controller hotplugging a reality, but to also remove any global state from the controller backend.
|
||||
Usually global state in any software is considered very bad, as it makes the program unpredictable, unreliable, and makes future code modifications unnecessarily complex.

## #4 [Cheats Support](https://github.com/citra-emu/citra/pull/4406) by [B3N30](https://github.com/b3n30)
|
||||
|
||||
At first, we were nervous about including cheats in the survey as we have a long history with cheat codes not working on Citra.
|
||||
But we added it anyway, since we were confident that if the people wanted cheat codes, we could finally resolve the long standing bug that kept cheat codes from working correctly.

|
||||
Along the way, [wwylele](https://github.com/wwylele) found that the way memory is handled in Citra wasn't truly accurate to how the hardware works.
|
||||
What started with a routine clean-up to remove global memory, ended with [wwylele](https://github.com/wwylele) [rewriting](https://github.com/citra-emu/citra/pull/4392) how almost all of the memory works in Citra!

|
||||
|
||||
When users started testing out games to see what broke and what got fixed, they also took to rebasing makotech222's [old cheat code support](https://github.com/citra-emu/citra/pull/2063) and tested to see if cheats were working again, and surprisingly they were.

|
||||
Word spread quickly that cheat codes were now working again, so after finishing controller hotplugging support, [B3N30](https://github.com/b3n30) worked on implementing cheat code support in Citra.
|
||||
He based his implementation on the old PR, but vastly improved it by rewriting many parts and fixing the many design flaws it had.

||||
Thanks to another developer [zhaowenlan1779](https://github.com/zhaowenlan1779), who implemented the [UI](https://github.com/citra-emu/citra/pull/4610) for cheats, the full cheat code support is now available in latest Nightly and Canary builds.

## #5 Custom Texture Support
|
||||
|
||||
As you've seen thus far, we've had our hands full between Pokémon X/Y, cheats, controller rewrite, and more.
|
||||
While we still want this feature, it's currently not in development, and we don't have any estimate for when someone will add it either.
|
||||
Stay tuned, as the open nature of the project means that this can change at a moment's notice.

Developer [jroweboy](https://github.com/jroweboy) picked up this task back in November, but ran into a roadblock just as he was about to finish it.
|
||||
There was some bug in the code, due to which games just weren't accepting the mic input, but after reviewing it several times and debugging it, he just couldn't figure out why.

By reviewing the differences in the two code, jroweboy found that he mixed up bits and bytes for the size of mic_data, a silly oversight, so the mic implementation wasn’t copying enough data to the game.

The most notorious and common system file is the shared font that games could load and use to render text, but ever since [B3N30](https://github.com/b3n30) added a custom font for Citra, the number of crash reports has dropped dramatically.

Since the beginning, Citra has always worked to recreate the *entire* 3DS ecosystem, so this marks a special occasion where almost every game is functional without needing to dump additional files.

|

For a long while now, Citra has only supported decrypted ROM dumps, not encrypted ones.
|
||||
Normally, the ROM dumping process would make use of secure keys in the 3DS system and generate decrypted ROMs as output.
|
||||
But supporting encrypted ROMs meant that we had to first extract these keys from the 3DS and then make Citra use them to read and decrypt encrypted ROMS on-the-fly.

|

Before we even got to implementing stuff on Citra's end, we had a major obstacle.
|

Until now, not much research had been done to figure out how to obtain these keys all together.
|

Developers [wwylele](https://github.com/wwylele) and [B3N30](https://github.com/b3n30), did the necessary research and slowly implemented support for encrypted ROMs.
|

Users can now follow the guide [here](https://github.com/citra-emu/citra/wiki/AES-Keys) to obtain these encryption keys, upon which Citra will be able to read encrypted ROMs or install encrypted CIAs directly.

### [Add Play Coins](https://github.com/citra-emu/citra/pull/4209) by [zhaowenlan1779](https://github.com/zhaowenlan1779)
|
||||
|
||||
For a long time, users have requested an option to add more `Play Coins` in Citra.
|
||||
`Play Coins` are a feature on the Nintendo 3DS.
|
||||
The player can obtain them by walking; players earn 1 coin for every 100 steps taken and can earn 10 coins daily, for a maximum of 300 in their bank at any given time.
|
||||
For a long time, users have requested an option to add more Play Coins in Citra.
|
||||
Play Coins is a 3DS feature that is intended to reward players for being physically active by counting steps taken while the console is in one's pocket, using motion tracking.
|
||||
The system rewards a Play Coin for every 100 steps, up to 10 coins per day, and up to 300 total.
|
||||
These can then be redeemed in various games.
|
||||
Citra can't track your device's movement, so the ability to add Play Coins through Citra's UI would be helpful for anyone wanting to play games that use them.
|
||||
|
||||
While attempts were made to implement this in the past, the code behind the implementation wasn't any good.
|
||||
[zhaowenlan1779](https://github.com/zhaowenlan1779) did some research into the `ptm` service, which was responsible for `Play coins` and implemented this long-requested feature.
|
||||
With this, Citra users now have **42** play coins by default and can add more coins up to **300**.

To further improve TAS ([Tool-assisted Speedrunning](https://en.wikipedia.org/wiki/Tool-assisted_speedrun)) on Citra, developer [zhaowenlan1779](https://github.com/zhaowenlan1779) implemented the `Frame Advancing` feature.
|
||||
Frame advancing is a commonly used TAS feature which basically means running the game frame by frame. TASers use this feature to press exact buttons at the exact frames.
|
||||
Furthermore, he added an `init time` field to the CTM header, that ensured RNG consistency when replaying a CTM (Citra TAS Movie) file.([here](https://github.com/citra-emu/citra/pull/4267))

While work on DSP LLE was progressing sluggishly and no one was actively working on audio related improvements, developer [RoadrunnerWMC](https://github.com/RoadrunnerWMC), unknowingly stumbled upon a bug in our DSP HLE implementation which was causing broken audio in Luigi's Mansion 2.

He had a hunch that this could be happening due to incorrect address masking, similar to a bug that had been found in Dolphin some time earlier.

He was successfully able to fix that issue but, as his implementation wasn't hardware tested, we couldn't confirm if that was indeed the way to fix it.

His fix was to mask away the **lowest 2 bits** of physical audio buffer addresses, but after multiple hardware tests on different consoles, it was found that masking the **lowest 4 bits** was actually the correct mask for all audio formats.

This fixed buggy audio in games like Luigi's Mansion - Dark Moon, The Amazing Spiderman, Metroid Prime Federation Force, and a few others.
