MVP06-Plus

MVP06-Plus

MVP 06 NCAA Baseball on Windows, and on SteamOS (Linux) through Proton, built on Mad Dog's PC port of the Original Xbox game. spy_jam's MVP06-Plus keeps Xbox controller support and adds PlayStation controller support with the PS2 release's full control layout and button labels, and experimental GameCube controller support. Includes a launcher for easy installation, also providing a save backup menu and display settings.

You need your own copy of the Xbox game. No game files or game art are included. The Launcher builds what's needed from your own discs.

Features

• PlayStation controllers with the PS2 release's full control layout and stick handling, analog button pressure and rumble.
• GameCube controllers (experimental) through a Wii U / Switch adapter: all 4 ports and rumble, with GameCube stick deadzones, C-stick and analog trigger handling. There was no GameCube MVP 06, so the layout follows MVP 2005's GameCube release as closely as 06 allows.
• Button art to match your controller: PS2 buttons in menus and in-game, made from your own MVP 06 PS2 disc, and GameCube buttons made from MVP 2005's GameCube art (both optional).
• MVP06-Plus Launcher: install from your discs, launch the game, restore save backups, adjust display settings.
• Fixes: a shader cache to prevent mid-game stutter, and SteamOS support through Proton.
• Save backups: a full save backup menu in the Launcher. Your saves are backed up automatically when the game starts, keeping the latest 30 backups by default, and you can view and restore them in the Launcher.

Compatible controllers

• DualSense, DualShock 4 — PS2 button art and controls
• DualShock 3 — PS2 button art and controls, with pressure-sensitive buttons (on Windows, through DsHidMini in SDL mode)
• Xbox 360, Xbox One and Xbox Series controllers — Xbox button art and controls, as the original
• GameCube controllers (official adapter, or a third-party adapter in Wii U mode) — GameCube button art and experimental controls
• Other controllers (Switch Pro and most others SDL supports) — Xbox button art and controls

Button art follows the controller connected when the game starts. Without the art sets, PlayStation and GameCube controllers still use their own control layouts, with Xbox buttons shown.

Install

1. Download MVP06-Plus-Beta-1.zip from Releases and unzip it anywhere. Everything stays in that folder: nothing goes into Program Files or the registry, and desktop shortcuts are only made if you ask.

2. Run MVP06-Plus-Launcher.exe and choose your discs:

   • Xbox (required): a Redump .iso, .xiso, or a folder of extracted files.
   • PS2 (optional, for PS2 art): your MVP 06 NCAA Baseball PS2 disc, .iso, or .chd with MAME's chdman (the Launcher finds it, or asks where it is). Only the 4 files the art needs are read from it.
   • Experimental GameCube support (optional): tick it for GameCube button art. There was no GameCube MVP 06, so the art is made from MVP 2005's: choose your MVP 2005 GameCube disc and MVP 2005 Xbox disc (only the files the art needs are read from each), or just your MVP05-Plus folder if it has GameCube art. It takes a minute or two.
   • Already have an MVP 06 gc_icons or ps2_icons set? Choose its folder or .zip instead.

3. Press Launch MVP 06. From then on, the Launcher opens on what's installed, with Launch. To quit the game, press Esc (it asks first).

Windows may warn that the Launcher is from an unknown publisher: choose More info → Run anyway.

Setting up controllers

• GameCube adapter on Windows: give it the WinUSB driver with Zadig, as for Dolphin (select WUP-028, WinUSB, Replace Driver). Third-party adapters: set the switch to Wii U.
• PlayStation and Xbox controllers: connect by USB or Bluetooth as usual.

SteamOS (Proton)

Add MVP06.exe to Steam as a non-Steam game, run with Proton. For the GameCube adapter, turn off Steam's own GameCube adapter support and set the launch options (with your folder's path):

sh -c 'B="/home/deck/Games/MVP06-Plus/gcbridge"; chmod +x "$B"; "$B" & exec "$@"' sh %command%

Adding to Steam (optional)

1. In Steam: Games → Add a Non-Steam Game to My Library, and choose MVP06.exe.
2. Playing with a PlayStation or Switch controller? In the game's Properties → Controller, choose Disable Steam Input. Otherwise Steam passes it to the game as an Xbox controller, with the Xbox layout and buttons.
3. On SteamOS, also follow the Proton steps above.

MVP06-Plus Launcher

• Install, which becomes Play once the game's installed: your discs in, then what's installed (checked each start), Launch MVP 06, and which controllers Windows sees right now, including whether the GameCube adapter has the WinUSB driver it needs.
• Saves: Current saves, and Backups by date. Restore single saves or a whole date; your saves become a backup first, so a restore can be undone.
• Settings: display mode, aspect ratio (16:9, or 4:3 with black bars at the sides), resolution (default: fullscreen at your desktop's resolution), render scale, frame rate cap, texture filtering, VSync, Xbox 720p mode; and desktop shortcuts for the game ("MVP 06 Plus") and the Launcher, if you want them.

Everything is also in mvp06-settings.toml. Plus adds gamecube_layout, gamecube_icons, playstation_layout, playstation_icons (all on) and save_backups (30).

Building from source

Windows x64 with Visual Studio's C++ tools and Windows SDK, LLVM Clang, CMake 3.25+ and Ninja. Put your Xbox files in assets/ and run Build-Source.cmd from an x64 Native Tools Command Prompt. Details: docs/MVP06-HANDOFF.md; making a release: docs/RELEASING.md.

Button art by hand (Python 3 with pip install pillow numpy scipy opencv-python-headless):
