rom_patcher library

A Dart library for applying ROM patch files in IPS, BPS, and UPS formats.

This library provides functionality similar to the Floating IPS (FLIPS) program and the Rom Patcher JS library, allowing you to apply patches to ROM files in memory without requiring file system access.

Supported formats:

  • IPS (International Patching System)
  • BPS (Binary Patch System)
  • UPS (Unified Patch System)

Example usage:

import 'package:rom_patcher/rom_patcher.dart';

// Apply a patch with auto-detection
final patchedRom = applyPatch(originalRom, patchData);

// Apply a specific format
final patchedRom = applyIps(originalRom, ipsPatchData);
