- [Library](https://ps5emulatorwindows.com/library.md): The indexed catalog: 400+ owned titles graded Stable, Beta, or Test, with per-game setup notes.
- [Protocol](https://ps5emulatorwindows.com/protocol.md): The ordered setup path: install, firmware, boot, index, controller — with fixes attached.
- [Reference](https://ps5emulatorwindows.com/reference.md): The engineering shelf: method, Vulkan, CPU, and shader-cache references behind every rating.
- [Compat](https://ps5emulatorwindows.com/compat.md): What the three ratings promise, and which titles currently hold Stable.
- [Hardware](https://ps5emulatorwindows.com/hardware.md): The sizing shelf: minimum vs recommended, and how VRAM decides resolution.
- [Lexicon](https://ps5emulatorwindows.com/lexicon.md): The vocabulary shelf. Two terms defined precisely; every other page cites them.
- [Diff](https://ps5emulatorwindows.com/diff.md): Two honest comparisons: generation gap and renderer choice, with trade-offs stated.
- [Log](https://ps5emulatorwindows.com/log.md): The lab notebook shelf: method first, so every rating change is auditable.
