Build

# Build (GUI + CLI)
dotnet build src/NeversoftMultitool/NeversoftMultitool.csproj

# Build and run tests
dotnet build tests/NeversoftMultitool.Tests/NeversoftMultitool.Tests.csproj
tests/NeversoftMultitool.Tests/bin/Debug/net10.0/NeversoftMultitool.Tests.exe

Usage

GUI Mode (Windows)

Run the executable with no arguments to launch the WinUI 3 interface:

dotnet run --project src/NeversoftMultitool -f net10.0-windows10.0.19041.0

The GUI provides tabs for each format type with drag-and-drop file selection and batch processing.

CLI Mode

# On Windows (from GUI build), use --no-gui or a subcommand to enter CLI mode
# On any platform (from CLI build):
dotnet run --project src/NeversoftMultitool -f net10.0 -- <command> [options]

Extract PSX Textures

NeversoftMultitool psx <directory> [-o output] [--subdirs] [-v]

• <directory> - Path to directory containing .psx files
• -o, --output - Output directory (default: output)
• --subdirs - Create subdirectories per .psx file
• -v, --verbose - Show per-file details

Convert RLE/BMR Bitmaps

NeversoftMultitool rle <directory> [-o output] [-w 512] [-v]

• <directory> - Path to directory containing .rle/.bmr files
• -o, --output - Output directory (default: output)
• -w, --width - Image width in pixels (default: 512)
• -v, --verbose - Show per-file details

Extract Archives

NeversoftMultitool archive <file> [-o output] [-v]

• <file> - Path to archive file (.wad, .pkr, or .pre)
• -o, --output - Output directory (default: output)
• -v, --verbose - Show per-file extraction progress

Architecture

The project uses multi-targeting to produce both a cross-platform CLI and a Windows GUI from a single codebase:

• net10.0 - Cross-platform CLI using System.CommandLine + Spectre.Console
• net10.0-windows10.0.19041.0 - WinUI 3 GUI with Mica backdrop

Shared format logic lives in Core/ and is used by both targets. GUI code in App/ is excluded from cross-platform builds via conditional compilation (#if WINDOWS_GUI).
