Let’s walk through a trivial mod: changing the door in the "Village Farm" (r101) to lead to "The Castle Throne Room" (r210) instead of the "Village Square."
Step 1: Extract the original Layout.bin from your RE4 installation (found in bio4/Image/).
Step 2: Drag Layout.bin onto RE4txt.exe. This generates a file called Layout.txt.
Step 3: Open Layout.txt in a code editor (like Notepad++). Search for r101.
Step 4: Find the transition entry:
[Transition_04] SourceRoom = r101 TargetRoom = r110 (Village Square)
Step 5: Change TargetRoom = r210.
Step 6: Crucial Step: Adjust the target spawn point. If you don’t change the coordinates, Leon will spawn inside a wall. Set TargetX = -1500, TargetY = 2000, TargetZ = 500 (using known coordinates from the Trainer).
Step 7: Save Layout.txt. Drag it back onto RE4txt.exe to generate a new Layout.bin.
Step 8: Copy the new Layout.bin back to the Image folder. Play the game.
The structure varies slightly between platforms, but the core layout is consistent.
| Offset (bytes) | Size | Type | Description |
|----------------|------|------|-------------|
| 0x00 | 4 | uint32 | Magic/Version ID (e.g., 0x00000100 for GC/PC) |
| 0x04 | 4 | uint32 | Number of entries (rooms/entities) |
| 0x08 | 4 | uint32 | Offset to entry table (usually 0x20) |
| 0x0C | 4 | uint32 | Unknown (possibly total size) |
| 0x10 | 16 | char | Game/engine signature ("RE4LAYOUT" sometimes) |
After the header, each entry (record) is typically 32–64 bytes and contains:
| Field | Size | Description |
|--------|------|-------------|
| Room ID | 2 bytes | e.g., r106, r207 |
| File offset | 4 bytes | Offset to .rso or .evd data in the bigfile |
| Flags | 2 bytes | Load flags (lighting, enemy spawn, cutscene) |
| Entity count | 2 bytes | Number of objects/enemies |
| Script ID | 2 bytes | Index of linked script file |
| Pad/Unknown | variable | Alignment bytes |

Here’s a solid, informative post about the layout.bin file for Resident Evil 4 (typically referring to the original 2005 release and its PC ports, including the Ultimate HD Edition). You can use this on a forum, blog, or modding community.
Title: Understanding layout.bin in Resident Evil 4 – What It Is and How to Use It
If you've dug into the files of Resident Evil 4 (PC), you've likely come across layout.bin. At first glance, it looks like just another data file, but for modders and advanced users, it’s one of the most important files in the game directory. Let’s break down what it does, why you shouldn’t just delete it, and when you might need to replace it.
