However, there's always room for more emulators! While Panda3DS was initially a mere curiosity, there's many different concepts I would like to explore with it in the future, such as:
 
 - Virtualization. What motivated the creation of this emulator was actually a discussion on whether it is possible to get fast 3DS emulation on low-end hardware such as the Raspberry Pi 4, using the KVM API. At the moment, Panda3DS is powered by Dynarmic rather than using virtualization, but this is definitely a concept I want to explore in the future.
