libfpv brings Betaflight into familiar game worlds. Plus: a Goggles 3 viewer gives more computers a spectator seat.
A familiar game world looks rather different when you can explore it by quad. Forget the prescribed route for a moment: which gap would you try first? That is the lovely invitation behind Hammerill’s libfpv project, with integrations for Super Mario 64 and GTA IV.
There is a real-world wrinkle behind the fun. Hammerill says flying an FPV mod in GTA V helped inspire him to buy an Air65 II. Then his first real whoop exposed something his game sessions had let him sidestep: he had disabled arming and never learnt that part. Flying the sticks and knowing what your switches do are not quite the same achievement.
More of the quad, not just the view
His answer is libfpv: a reusable software library that lets game modders bring in a drone simulation rather than rebuild one for each world. It runs Betaflight 2025.12 through SimITL, a simulation layer. The game supplies the scenery, collision geometry and rendering; libfpv supplies the flight-simulation machinery.
The interesting bit for pilots is the setup connection. Desktop integrations can connect to Betaflight Configurator, bringing rates, modes and arming into the picture. Rates govern how stick movement translates into rotation; modes and arming bring the switches back into the conversation. That gives this project a more intriguing ambition than simply attaching a flying camera to a game.
Each game still needs its own integration: the GTA IV project lists Steam’s Complete Edition 1.2.0.59 as its only tested game version, and browser builds cannot connect to Configurator.
For modders, the attraction is reuse. For the rest of us, it is the prospect of revisiting somewhere familiar with a completely different set of movements available. A beloved level need not stop being interesting just because you know where the doors go.
Hammerill says AI handled the technical conception and implementation, with him testing and guiding fixes rather than reviewing all the code. He is still reworking physics to reduce floatiness. Real Betaflight is an interesting foundation, not proof of realistic flight or training transfer.
Our take: enjoy this as an inventive game-world flying project, not a substitute for learning your real quad’s setup. Start with the creator’s account and the film below; there is plenty to be curious about before making an installation project of it.
Watch: Mario, with a different control scheme
Hammerill’s Beating Mario 64 with an FPV drone is the official full playthrough, not a quick setup tutorial. Settle in or dip into it for the game-world appeal behind the project.

A spectator seat for Goggles 3
If your companion would rather see the flight than watch you stand very still, Goggle 3 LiveView is worth a look. The community project receives DJI Goggles 3 video over USB for viewing on a computer.
The new arrivals are a Linux single-feed preview and Windows x64 support for the separate Multi app. Multi offers up to four channels, individual recordings and a recorded mosaic: useful scope for sharing the view without passing the goggles around.
The separate Multi app’s Mac interface, idle with four unassigned channels and zero USB goggles connected—not a Windows screenshot or a live four-goggles test. Image: Goggle 3 LiveView contributors, 2026 — full MIT licence.
Choose by platform, not just the name. Multi supports Apple Silicon Macs on macOS 14+ and Windows 11 x64 or Windows 10 22H2 x64; Linux is single-feed only.
The Linux preview has only been tested on Ubuntu 24.04 x64 with X11/XWayland, and physical Goggles 3 reception on Linux remains unverified. Packages lack commercial signing, and Mac builds are unnotarised. This is a spectator tool: keep the goggles as your primary flying display.
Which game world would you most like to explore by quad—and what would be your first gap?
