The Lion King (1997) Windows Fix

An unofficial compatibility fix for the Windows version of Disney's The Lion King included in the European Disney's Classic Video Games collection (1997).

It makes the original game run cleanly on modern Windows while preserving its art, audio and native Win32 code. No game files are included.

What it fixes

• removes the false “must run in at least 256 colours” rejection;
• repairs the EPFS file-open check used during startup;
• replaces an obsolete BIOS clock call and four privileged CPU instructions;
• renders the 8-bit DirectDraw game correctly in borderless fullscreen;
• preserves the intended 4:3 image and limits presentation to 60 FPS;
• keeps music and sound working from a portable folder;
• provides stable taskbar, Alt+Tab and live-preview behaviour;
• exposes the original Properties panel with F2;
• makes its Keyboard and Joystick tabs safe on 64-bit Windows;
• restores a proper English exit confirmation with Esc;
• hides the permanent busy cursor during play and restores it for dialogs;
• launches through a temporary short path to avoid the original MIDI command buffer overflowing on long modern folder names.

Installation

1. Download the latest release ZIP and extract it.
2. Prepare a writable copy of the original game:
   • for the supported 1997 European Disney Classic Video Games disc, mount the disc or ISO and copy its complete LIONKING folder to your computer;
   • you do not need the disc's DIRECTX folder, the other games or the files in the disc root;
   • if you already have a complete installation containing LIONW.EXE, you can use that folder instead.
3. Copy every file from the extracted release's patch folder into that writable LIONKING folder, beside LIONW.EXE.
4. Run Install patch.cmd once.
5. From then on, start the game with Play Lion King.exe.

The installer accepts only the exact supported executable, verifies every patch component, creates LIONW.EXE.gamevault-original, applies the known byte changes and verifies the finished result. An unknown executable is never modified.

To undo the executable changes, run Restore original.cmd. Compatibility files are deliberately left in place rather than silently deleted.

Supported executable

• Original SHA-256: 3E99DC48A4B347833E3857A13E0635AB9C5A262BBCD2DBB5304A7BBE0E45DEF3
• Patched SHA-256: AD28370116F86CEAAB87D77B66533018716CACB6E3E010ED63E3A053BA327EC8

If your hash differs, stop. It may be another legitimate edition, but this release has not been proven safe for it.

Using the game

• Press F2 while the game is running to open its original Properties panel. From there you can choose the difficulty and view or reassign the keyboard and joystick controls.
• Press Esc to pause and choose whether to exit the game.
• Press Alt+Tab to switch normally between the game and other applications.

Difficulty and remapped keyboard/joystick controls work during the current session. This 1997 release recreates its default bindings on every launch, so custom bindings are not persistent.

One small Windows quirk remains: after clicking the taskbar icon, the taskbar can occasionally stay visible until the game regains focus. Pressing Alt+Tab away and back restores the borderless presentation.

What the download contains

• ddraw.dll: the open-source GameVaultDraw compatibility layer;
• GameVaultDraw.ini: borderless 4:3 and 60 FPS defaults;
• Play Lion King.exe: a native, console-free short-path launcher;
• safe install and restore scripts.

It does not contain LIONW.EXE, music, artwork, archives, disc images or any other proprietary game data. You must supply your own legitimate copy.
