An innovative development has emerged in the gaming community with the introduction of an open-source, unofficial Nvidia GeForce Now client tailored for Nintendo 3DS consoles. This new homebrew application, named Kasumi, allows gamers to stream PC titles directly on their dual-screen handheld devices, including the Nintendo 3DS, 3DS XL, and 2DS XL. Users can also customize their control schemes and connection settings to enhance their gaming experience.
Features and Functionality
Kasumi is designed for jailbroken Nintendo 3DS devices equipped with a built-in video decoder. It opens the door to a vast library of games available on GeForce Now, encompassing titles from platforms such as Steam, Epic Games, and Ubisoft Connect. Players can enjoy the full range of Nvidia’s RTX technologies, including DLSS, frame generation, and Reflex, by simply linking their third-party accounts to their GeForce Now profile.
The architecture of Kasumi allows the 3DS to primarily manage video and audio decoding along with controller input, while the heavy lifting of game rendering is performed on Nvidia’s servers. However, it is important to note that games requiring exclusive mouse and keyboard controls may not be playable due to the limitations of the console.
As the console does not run games locally, the quality of the gaming experience is heavily influenced by the user’s Wi-Fi and internet connectivity, as well as their proximity to Nvidia’s GeForce Now servers. The 3DS’s low resolution of 960×540 for video streaming and its 400×240 display means that users will not be able to access the full capabilities of GeForce Now’s 5K Ultimate tier.
The developer of Kasumi has intentionally designed the application to accommodate the limitations of the Nintendo handheld. This includes capping the frame rate at 30fps and the bitrate at approximately 1Mbps, as the 3DS was originally built for 30fps video playback, and its 2.4GHz Wi-Fi adapter tends to lose packets beyond 1.2Mbps.
In terms of server latency, measurements taken by the modder indicate a range between 60ms and 80ms. To mitigate potential disruptions during gameplay, the mod incorporates a buffer that holds one or two frames, ensuring a smoother experience even when Wi-Fi connectivity is less than ideal. Users are also provided with live PING and frame rate metrics to monitor their gaming performance.
Beyond performance, Kasumi offers a user-friendly control scheme specifically crafted for the 3DS. Gamers can configure button mappings on a per-game basis and utilize gyro aiming features. The touch screen also serves as L3 and R3 buttons for titles that require these inputs.
Importantly, Kasumi is compatible with the free version of GeForce Now, which includes the waiting queue and a one-hour session limit. Users can close their console lids without losing their place in the queue, receiving notifications through indicator lights when it’s their turn to play.
While Kasumi presents a promising avenue for gaming on the Nintendo 3DS, it remains in active development as an unofficial mod. As such, users may encounter some inconsistencies and rough edges as the project evolves.
