# xex2tractor

A tool for extracting and inspecting Xbox 360 XEX2 executable files, written in Rust.

## Usage

### Inspect

Display XEX2 file information (headers, security info, etc.):

```sh
xex2tractor inspect <file.xex>
```

#### Example Output

```
=== XEX2 Header ===
Magic:            XEX2 (0x58455832)
Module Flags:     0x00000001 [TITLE]
Header Size:      0x00003000 (12288 bytes)
Reserved:         0x00000000
Security Offset:  0x00000090
Header Count:     15

=== Optional Headers (15 entries) ===

[ENTRY_POINT] 0x824AB748
[IMAGE_BASE_ADDRESS] 0x82000000
[DEFAULT_STACK_SIZE] 0x00080000 (524288 bytes)
[SYSTEM_FLAGS] 0x00000400 [PAL50_INCOMPATIBLE]

[EXECUTION_INFO]
  Media ID:        0x2D2E2EEB
  Title ID:        0x535107D4
  Version:         0.0.0.2
  ...

[FILE_FORMAT_INFO]
  Encryption:  Normal (AES-128-CBC)
  Compression: Normal (LZX)
  Window Size: 0x8000 (32 KB)
  ...

=== Security Info ===
Header Size:          0x00000F34 (3892 bytes)
Image Size:           0x00920000 (9568256 bytes)
RSA Signature:        2C94EBE6...11A6E8AA (256 bytes)
Image Flags:          0x00000008 [XGD2_MEDIA_ONLY]
Load Address:         0x82000000
Region:               0xFFFFFFFF [ALL REGIONS]
Allowed Media Types:  0x00000004 [DVD_CD]
...
```

### Extract

Extract the decrypted and decompressed PE image from a XEX2 file:

```sh
xex2tractor extract <file.xex> [output.exe]
```

If no output path is given, defaults to the input filename with `.exe` extension.

#### Example

```sh
$ xex2tractor extract default.xex default.exe
Encryption:  Normal (AES-128-CBC)
Compression: Normal (LZX)
Extracted PE image (9568256 bytes) -> default.exe
```

Supports:
- AES-128-CBC decryption (retail, devkit, and XEX1 master keys)
- No compression, basic (zero-fill), and normal (LZX) decompression
- PE header verification (MZ signature, PE signature, POWERPCBE machine type)

## Building

```sh
cargo build --release
```

## Testing

Place a sample XEX2 file at `tests/data/default.xex`, then run:

```sh
cargo test
```
