# FNV-nx: an experimental Fallout: New Vegas PC-to-Switch recompilation

> FNV-nx investigates a native Nintendo Switch port of Fallout: New Vegas by translating PC x86 code ahead of time and implementing Windows ABI services and a Vulkan graphics path. The repository documents Ghidra analysis and diagnostic tests; the author reports a Switch hardware test that reached the game menu and opening movie, while gameplay loading remains unverified.
