01.Introduction: Farewell ePSXe
ePSXe relies on outdated plugins from the early 2010s. DuckStation is a modern, "All-in-One" emulator that eliminates the need for external video or audio plugins. Its killer feature, PGXP, completely transforms the visual fidelity of 32-bit classics.

02.Chapter 1: PGXP (Geometry Correction)
Ending the "Wobbly" Effect
The original PS1 lacked a high-precision Z-Buffer, causing floor textures to "dance" and character models to shimmer/jitter.
Navigate to Console Settings > Advanced > PGXP.
Enable "PGXP Geometry Correction."
This stabilizes geometry, making walls and floors appear solid and straight, similar to a high-end N64 or PC title of that era.
03.Chapter 2: Upscaling (4K Visuals)
Go to Graphics Settings > Enhancement settings.
Set Internal Resolution Scale to 4x (1080p) or 9x (4K).
DuckStation is highly optimized; even integrated laptop graphics can typically handle 1080p upscaling without dropping frames. Avoid heavy MSAA at high resolutions as it provides diminishing returns.
04.Chapter 3: .CHD Compression (Storage Efficiency)
PS1 titles in .BIN/.CUE format typically occupy ~700MB.
DuckStation supports .CHD (Compressed Hunks of Data).
This format compresses games down to ~300-400MB with zero loss in quality or loading speed. Use the tool chdman to convert your entire library for massive storage savings.
A1.Chapter 4: Widescreen Hack and Culling
Render 4:3 classics in 16:9 natively.
DuckStation accomplishes this by extending the camera's viewport.
Note: In certain titles (e.g., Crash Bandicoot), objects at the screen edges may "pop-in" because the game engine was never programmed to render assets outside the 4:3 area. If this immersion break bothers you, stick to the original aspect ratio with CRT filters.
A2.Chapter 5: Emulated CPU Overclocking
Titles like Driver 2 famously struggled to reach 20 FPS on original hardware.
Navigate to Console Settings > CPU Emulation.
Increase the "Emulated CPU Clock Speed" to 500% or higher.
This allows games to maintain a locked 30 FPS (or 60 FPS with specific patches) without increasing the actual game speed (turbo).
A3.Chapter 6: Texture Filtering (xBRZ)
- Nearest: Keeps the sharp, pixelated "Retro" look. - Bilinear: Smooths out the textures for a softer feel. - xBRZ Upscaling: An advanced algorithm that rounds off pixel edges to mimic an "HD Remaster." This is controversial among purists—test it to see if it suits your taste.
A4.Chapter 7: BIOS Management
An official BIOS file is required (e.g., scph1001.bin).
DuckStation performs an MD5 checksum on your BIOS to ensure it is not corrupted and matches known reliable region dumps.
Chapter 8: The Rewind Feature
Enable Rewind in the hotkey settings.
Mapped to a single key, this allows you to undo a mistake (like a missed jump in Tomb Raider) by literally winding back time 5-10 seconds. It's the ultimate modern quality-of-life tool for retro gaming.
Chapter 9: Big Picture UI Mode
DuckStation features a stunning "Big Picture" interface designed for use on TVs with a controller, similar to the Steam Deck or modern consoles.
Access it via Settings > Big Picture Mode.
Chapter 10: Android Compatibility
The Android port of DuckStation is as robust as the PC version.
It supports Bluetooth controllers and features a fully customizable touch overlay. You can synchronize your save files between PC and mobile using tools like Syncthing or Google Drive.
