BSAOpt vs Reloaded-II

BSAOpt is free, open-source Windows software for managing and recompressing BSA archives. It presents archive contents like directories, allowing files inside to be addressed directly, and can deduplicate files. Copy, Pack, Unpack, and Convert operations depend on the selected input and output. The listing says compression is roughly 5% better for files and 20% better for WAV files. Supported formats are BSA and ZIP, with archive extraction and mod packaging included. Version history lists Morrowind support, Fallout compatibility, and Xbox-type archives. Version 1.6.3 added recognition for XWM, FUZ, OGG, GID, and PEX files. Optional logs and a broken-header dialog can attempt recovery from corrupt BSAs. It is partially multi-threaded, supports 32-bit and 64-bit Windows Vista or later, and requires administrator execution when UAC is enabled. The listed version is 1.6.3, updated 14 January 2013.

Reloaded-II is a free, modular framework for creating mods for x86 and x64 games. Mods can be written in .NET and C#, and native mods are also supported; the project says they can use libraries and NuGet packages while running in isolation. The loader includes dependency ordering, early hooks, hot reload, real-time console and file logging, and Visual Studio debugging and profiling support. Its launcher manages multiple games and per-game mod sets, with built-in configuration, automatic updates and a mod downloader that offers one-click downloads on supported websites. The automatic installer installs Reloaded-II and runtimes in one click; the documentation says this usually takes under 30 seconds. The project says it does not modify game files and can be removed by deleting its folder. Windows users are directed to the installer, while Linux users are directed to a setup guide. Listed platforms include Windows, Linux via Wine or Proton, and macOS via Wine. The FAQ advises against using Reloaded-II with multiplayer games because games with effective anti-cheat may ban users.
