- Reported result
- Works. This is the directory's source-based outcome classification.
- Independent confirmation
- Not reported.
- Human work and limitations
- The project explicitly requires CPU overclocking for stability. The author emphasizes that the game is translated, not emulated, and relies on hardware-specific logs for performance metrics.

## What was done

NFS Carbon NX translates the Xbox 360 version of Need for Speed: Carbon to run natively on Nintendo Switch hardware using ReXGlue and a custom Vulkan renderer. It requires CPU overclocking and specific memory configurations to function.

NFS Carbon NX enables the native execution of the Xbox 360 release of Need for Speed: Carbon on the Nintendo Switch. The project utilizes [ReXGlue](https://raw.githubusercontent.com/zofo007/nfs-carbon-nx/HEAD/README.md) to translate the game's PowerPC-based `default.xex` code into ARM64, while a purpose-built Vulkan renderer handles GPU commands via NVK. The author reports that this is a translation rather than an emulation layer. The project supports both Standard and Collector's Editions, with the latter currently in beta. Performance is heavily dependent on CPU overclocking, as the game's code is limited by the Switch's CPU performance; stock clock speeds result in audio stuttering and poor frame rates. Users must provide their own NTSC-U game files and ensure the environment provides approximately 3.2 GB of memory with a 39-bit address space to prevent thread creation failures. While core features like career mode and saves are functional, the author notes that Collector's Edition has undergone fewer hours of testing and specific DLC item unlocks remain largely untested. Claude Sonnet 5.5 is credited as a co-author on documentation and release commits.

## Reproduce it

```
Launch the NRO with title override on a Switch running Atmosphere. Ensure the environment provides 3.2 GB of memory and 39-bit address space. Use a clock manager to apply CPU/GPU/memory overclocks (reference: 1428/768/1600 MHz).
