TP.exe Level Music Patch - Usage Guide

These scripts fix Theme Park World's in-park level music, which on modern Windows either never plays, or stops permanently after the first tick of a level. See TPW-LevelMusic-Investigation.md for the full technical writeup of the three underlying bugs (v1/v2/v3).

Requirements

• Python 3.
• A supported 32-bit TP.exe from Theme Park World / Sim Theme Park.
• Your own installed copy of the game.

This project does not include or distribute TP.exe, TP.icd, or any game assets.

The patcher is safe to run on:

• a completely unpatched TP.exe
• a TP.exe already partially patched by the older v1/v2 scripts
• an already fully patched TP.exe

If the patch is already applied, the script will detect that and do nothing.

TL;DR - just fix my game

The patcher modifies your existing TP.exe and creates a timestamped backup before writing anything.

Windows PowerShell

From this repository folder:

py .\Patch-TPW-LevelMusic-Combined.py "C:\Program Files (x86)\Bullfrog\Theme Park World\TP.exe"

If the game is installed under Program Files, run PowerShell as Administrator.

Preview without changing anything:

py .\Patch-TPW-LevelMusic-Combined.py --dry-run "C:\Program Files (x86)\Bullfrog\Theme Park World\TP.exe"

Linux / macOS terminal

If you are running the Windows version of the game through Wine or a Wine-style wrapper, patch the TP.exe inside that prefix/bottle.

Example default Wine path:

python3 ./Patch-TPW-LevelMusic-Combined.py "$HOME/.wine/drive_c/Program Files (x86)/Bullfrog/Theme Park World/TP.exe"

Preview without changing anything:

python3 ./Patch-TPW-LevelMusic-Combined.py --dry-run "$HOME/.wine/drive_c/Program Files (x86)/Bullfrog/Theme Park World/TP.exe"

For custom Wine prefixes, CrossOver bottles, Whisky bottles, Porting Kit installs, or other wrappers, replace the path with the actual location of your TP.exe.

Alternate-resolution executables

Compatible alternate-resolution executables can also be patched if their music-code signatures match.

TP_AltRes.EXE from the TPW-TPI-Fixes project has been tested successfully with the combined level-music patch.

TPW Patcher does not include or distribute TP_AltRes.EXE; users must obtain it from the original project.

What the patcher does

The combined patcher applies all three level-music fixes in one pass.

It will:

• detect whether your TP.exe is supported
• apply the fixes only if needed
• create a timestamped backup next to TP.exe
• verify every changed byte after writing
• print the exact rollback command for your backup

Rolling back

Use the exact backup filename printed by the script for your run.

Windows PowerShell

From the game folder:

Copy-Item "TP.exe.levelmusic-combined-bak-20260614-024502" "TP.exe" -Force

Linux / macOS terminal

From the game folder:

cp -f "TP.exe.levelmusic-combined-bak-20260614-024502" "TP.exe"

Example Wine path:

cd "$HOME/.wine/drive_c/Program Files (x86)/Bullfrog/Theme Park World"
cp -f "TP.exe.levelmusic-combined-bak-20260614-024502" "TP.exe"

Wrapper paths vary. Find the folder containing TP.exe, then restore the backup over it.

Validation checklist (after patching)

1. Start a fresh save, enter a level for the first time - level music should start immediately, with no need to leave and re-enter.
2. Exit and re-enter the same level - music should still play.
3. Switch to a different level - music should also play there on first entry.
4. Menu/lobby music should be unaffected.

Historical scripts

Earlier development used separate v1, v2, and v3 patchers plus compatibility/testing helpers.

This public release only requires:

• Patch-TPW-LevelMusic-Combined.py

The combined patcher is self-contained and supersedes the older per-stage scripts for normal use.

Troubleshooting

• "Permission denied" - run PowerShell as Administrator (needed when TP.exe is under Program Files).
• "Refusing to patch an unrecognized EXE layout/version" / "...fingerprint" - the script doesn't recognize this build of TP.exe (wrong version, already modified by something else, or corrupted). Run Test-TPW-PatchCompat.py against it for details. Do not force the patch.
• "already fully applied... No changes made." - your TP.exe already has all three fixes; nothing to do.
