Do I need the original game files to run WWF No Mercy Recompilation?

Yes. The project does not include the original game's assets, so you need your own copy.

Which ROM does it use?

It accepts only the USA Rev 1 release; the USA Rev 0 release and other regions are not accepted.

Where is the savefile stored?

On Windows, saves are stored in `%LOCALAPPDATA%\NoMercyRecompiled\saves\`.

About

WWF No Mercy: Recompiled uses N64Recomp to statically recompile the Nintendo 64 game WWF No Mercy into a native PC port. It runs on the N64ModernRuntime with RT64 as the rendering engine. The README labels it beta: the game boots, renders at high resolution, plays music and sound effects, takes keyboard and gamepad input, rumbles, and its cartridge flash save persists across sessions. It is the fifth project in the AKI wrestling recompilation family.

How it differs from the original

Adds widescreen support, in-game config menus with full input rebinding for keyboard and controller, and default mappings tailored to the AKI control scheme. High framerate support, Linux support and mod support are listed as planned.

Getting started

The repository and its releases contain no game assets, so the original game is required. Only the USA Rev 1 ROM is accepted; the USA Rev 0 release and other regions are rejected, and the port cannot run any arbitrary ROM. A Windows build is targeted, needing a GPU with Direct3D 12.0 (Shader Model 6) or Vulkan 1.2 and a CPU with SSE4.1. Assets load directly from the ROM with no extraction step, and adding a portable.txt file next to the executable keeps saves and config beside it.

Known issues & limitations

Multi-controller sessions are still being stabilized and can crash; single-controller or keyboard play is described as solid.
The first launch may pause briefly while shaders compile for the GPU.

Additional notes

No decomp: The README says no public decompilation of the game exists, so the project generates its own symbol metadata from a splat disassembly.
Static recompilation: The README defines static recompilation as automatically translating the original MIPS machine code into C compiled for modern PCs, and says this is not an emulator and not a decompilation.
