Every sim pilot has probably wondered what it would be like to fly a quad through a classic platformer, and that is exactly the idea behind this project. The maker is developing libfpv, a library that drops an FPV quad into whatever game it is applied to, and the first real test case is Super Mario 64 running under sm64ex.
Under the hood, libfpv builds on SimITL, the engine behind a sim called pr0p. It delivers realistic flight physics along with a full Betaflight firmware simulation, and the quad can be adjusted through an actual Betaflight configurator. Development moved remarkably fast: with great help from Claude Code running the Opus 5.5 model, the core library took roughly two hours to build and debug, and hooking it into sm64ex took only another half hour, during which the AI worked fairly autonomously. The maker also stayed well below the subscription usage limits on the 21 euro per month plan.
Two details stand out to me. Betaflight rates ship as the default, but the maker runs five33 rates everywhere, a nice touch of personal flavour. The whole thing is open source too, with both the sm64ex port and the library itself published on GitHub, and the maker is openly inviting contributions while looking forward to seeing people freestyle in the mod.
One open question remains: for now the project exists only as the sm64ex-fpv repository, and the maker warns the mod might be tricky to install. Wider game support is planned, and it will be interesting to watch the library grow beyond Mario.
