v0.2.1 Changes

New Features

• Combination bindings: bind any action to up to three buttons pressed together (for example L + R). Hold the buttons together when binding.
• Open the options menu from a controller with Back + Start (- and +). F10 still works on the keyboard, and both can be rebound.
• Rebindable tab switching in the options menu (LB / RB, Q / E), in a new Options tab of the rebind screen.
• Players 2-4 can share the keyboard: set their controller to Keyboard and give them keys of their own.

Fixes

• Options menu Select and Back now follow your controller bindings (they were swapped after rebinding confirm and back).
• Pressing - and + together no longer opens and immediately closes the options menu.
• The - / + combination no longer sends - or + to the game on its own (which could open Select World on the map).

Known issues

• Players 2-4 set to Keyboard start with no keys bound. Bind their keys (including World map → Enter course) before using Add/Drop Players.
• Prebuilt shader list not complete for worlds past World 1.
• Animations freeze after a resolution change in a level.
• Volcano Smoke is invisible in World 8-1
• Performance will be optimized more in the future.

Requirements

• Windows 10 or 11, 64-bit
• A CPU with AVX2 (Intel Haswell / 2013 or newer, any AMD Ryzen)
• A GPU with Direct3D 12 or Vulkan
• Your own dump of the PAL disc (SMNP01), revision 1: .rvz, .iso or .wbfs. The US disc will not work.

How to play

1. Extract the zip to a folder with about 1 GB free.
2. Run NSMBWCompiled.exe.
3. Pick your disc image when asked. It is extracted once, next to the game.
4. Optionally, pick a Dolphin HD texture pack folder.
5. In game, press F10 (or Back + Start on a controller) for settings: graphics, audio, controls. It opens automatically on first launch.

• One-time setup with no config files to edit
• Keyboard and gamepad support, with rebindable controls (including button combinations) and matching button prompts
• Dolphin HD texture packs work unchanged
• Full save from the world map at any time; Exit works in uncleared courses
