Smash 4 PC

Smash 4 PC

A native Windows port of Super Smash Bros. for Wii U, statically recompiled from the game's PowerPC code: the game's code is translated to C++ ahead of time and runs as native x86-64 code on a reimplementation of the Wii U's system libraries, with its GPU commands and shaders translated to Vulkan. No emulator.

Features

• Plays the game natively, from the update (v304, all fighters and stages) or the game's own v1.0, with DLC from your own DLC dump: Smash, 8-Player Smash and the game's other modes.
• Up to 4K and 5K, drawn at that resolution rather than upscaled, fullscreen or in a window.
• 60, 120 or uncapped frame rates: above 60 the game's frames are interpolated; the game itself runs at 60.
• Controllers: XInput, PlayStation, Switch Pro and other SDL pads, plus the keyboard. The first pad (and the keyboard) is the GamePad; every further pad is a Wii U Pro Controller, so 8-Player Smash works locally.
• Online on Pretendo Network: Smash's own online modes, with your Wii U's console files and your Pretendo ID, signed in from the launcher.
• Mods: content\ mods (Sm4shExplorer packs, SDCafiine mods, Cemu graphic packs), installed from a .zip, .7z or .rar in the launcher and switched on or off there.
• A launcher for the game, update and DLC folders, display settings, mods and online, and an in-game menu (Esc or a pad's Home button) for the frame counter, fullscreen and frame rate.

Install

1. Download Smash4PC-v0.1.0-Windows.zip from Releases and unzip it anywhere.
2. Run Smash 4 PC.exe and choose PLAY. It asks for your game folder (0005000010144F00), then the update (0005000E10144F00, recommended) and the DLC (0005000C10144F00, optional): the folders Cemu uses, dumped with Dumpling.
3. Play. Shaders compile the first time each is seen, then load from cache\ at start-up.

Needs Windows 10 or 11 (64-bit) and a GPU with Vulkan 1.3. The full guide (controls, mods, online, troubleshooting) is assets/smash/README.txt, also in the release zip.

Building from source

You need Windows, Python 3, Git, about 16 GB of RAM, and a folder holding this repository and a toolchain\ folder beside it with llvm-mingw, Ninja and CMake:

Smash4PC\
  toolchain\llvm-mingw\  toolchain\Ninja\  toolchain\CMake\
  upstream\              (this repository)

# Fetches and builds the dependencies once, builds the recompiler, translates your cross_f.rpx files and builds
# smash.exe (the update's code), smash-base.exe (the game's own) and the launcher into ..\Play.
.\upstream\tools\windows\build-smash.ps1 -Rpx '<update>\code\cross_f.rpx' -BaseRpx '<game>\code\cross_f.rpx'
# The release zip, in ..\dist.
.\upstream\tools\windows\package-release.ps1

The translated code (..\generated) and the programs built from it contain the game's code: don't upload them or attach them to issues.
