## Development
|
||||
|
||||
FearlessTobi began the development by leveraging the existing virtual rooms infrastructure from [Citra](https://citra-emu.org).
|
||||
Due to code similarities between yuzu and Citra, this tried and tested infrastructure easily became the foundation of this feature.

|
||||
Due to code similarities between yuzu and Citra, this tried-and-tested infrastructure easily became the foundation of this feature.
|
||||
|
||||
Now that the virtual rooms were taken care of, Tobi moved onto the `LDN` service and its protocols.
|
||||
Using the research and code from the [ldn_mitm](https://github.com/spacemeowx2/ldn_mitm) project, he implemented the necessary changes for yuzu instances to communicate with each other over these virtual rooms.
|
||||
While implementing, Tobi put an extra emphasis on ensuring no personal data like IPs was leaked to the other room members.
|
||||
|
||||
As the feature slowly matured, Tobi began leveraging yuzu's internal team of testers to test the feature across several titles for compatibilty and performance validation.
|
||||
And to prevent user IPs from being leaked when connected to rooms, Tobi changed the implementation to use fake IPs for routing.
|
||||
As the feature slowly matured, Tobi began utilizing yuzu's internal team of testers to verify the feature across several titles for compatibility and performance validation.
|
||||
|
||||
With the multiple testing iterations, various bugs and glitches were found.
|
||||
[german77](https://github.com/german77) relied on his own reverse-engineering and hardware tests, to debug these issues and fixed them all.

## Compatibility

We hope to slowly fix these over the course of next few months.

As with any new update, we've tested the feature internally, but our efforts can't compare to the community as a whole.
|
||||
We could have easily missed an edge case or some weird bug or issue among the vast collection of games with Local Wireless mode.
|
||||
So, please reach out to us on our [Discord](https://discord.gg/u77vRWY) and report any bugs you find, so that we can quickly address them.
