Foolsupdate / Psych Engine Setup

This repo contains both:

• a clean macOS Psych Engine app
• a patched macOS app with foolsupdate already applied
• the patch files by themselves
• the original zip archives for reference

Quick Start

If you just want to play foolsupdate on macOS, run this:

• psych-engine-foolsupdate/PsychEngine.app

From Terminal:

open "psych-engine-foolsupdate/PsychEngine.app"

If macOS blocks it:

1. Right-click psych-engine-foolsupdate/PsychEngine.app
2. Click Open
3. Click Open again on the warning

That is the easiest path. You do not need to patch anything manually if you use psych-engine-foolsupdate/.

What Each Folder Is For

• psych-engine/
  • Clean base Psych Engine app for macOS.
  • Use this if you want an unpatched copy.
• psych-engine-foolsupdate/
  • Ready-to-run macOS app with the foolsupdate patch already applied.
  • This is the main thing most people should launch.
• foolsupdate-patch/
  • Patch source files only.
  • Use this if you want to apply the patch yourself to a fresh app.
• archives/
  • Original zip files:
    • archives/PsychEngine-MacOS.zip
    • archives/foolsupdate_95899.zip

How To Run It

Easiest way

Launch:

• psych-engine-foolsupdate/PsychEngine.app

or:

open "psych-engine-foolsupdate/PsychEngine.app"

If you want the clean base engine instead

Launch:

• psych-engine/PsychEngine.app

or:

open "psych-engine/PsychEngine.app"

How To Apply The Patch Manually

You only need this section if you want to rebuild the patched app yourself.

1. Start from the clean app

Use:

• psych-engine/PsychEngine.app

2. Make a backup first

Copy psych-engine/PsychEngine.app before patching it.

This mod is buggy, so keeping a clean backup is strongly recommended.

3. Copy the patch into the app bundle

Copy everything from:

• foolsupdate-patch/Contents/Resources/

into:

• psych-engine/PsychEngine.app/Contents/Resources/

Finder method

1. Right-click psych-engine/PsychEngine.app
2. Click Show Package Contents
3. Open Contents/Resources/
4. Copy everything from foolsupdate-patch/Contents/Resources/ into that folder
5. Allow Finder to merge and replace files

Terminal method

cp -R "foolsupdate-patch/Contents/Resources/." "psych-engine/PsychEngine.app/Contents/Resources/"

After that, run:

open "psych-engine/PsychEngine.app"

If you want to keep the patched app separate, duplicate psych-engine/PsychEngine.app first and patch the copy.

Recommended Way To Use This Repo

If you are not developing or rebuilding anything:

1. Ignore psych-engine/
2. Ignore foolsupdate-patch/
3. Run psych-engine-foolsupdate/PsychEngine.app

Windows Notes

For Windows, use the original Windows-style release archive:

• archives/foolsupdate_95899.zip

After extracting it on Windows, run:

• bin/BFDI26.exe

Do not copy the Windows runtime files into the macOS .app bundle.

Known Issues

• foolsupdate is still buggy. Expect crashes, warnings, or odd scripting behavior.
• This repo has been cleaned up so the macOS app is much easier to launch, but the mod itself is not fully polished.
• Some packaging issues were fixed to make the patch usable on macOS.
• The folder typo VEE2/scipts was normalized to VEE2/scripts.

Short Version

If you only read one line, read this:
