The ePSXe PlayStation 1 emulator has recently introduced native support for CHD image files, marking its first major core update in over a decade. This update allows users to run highly compressed, lossless game files directly without needing external plugins or extraction tools. What are CHD Files?
Compressed Hunks of Data (CHD) is a lossless compression format originally designed for MAME arcade machines. It has become a gold standard for retro emulation because it:
Saves Significant Space: Compresses bulky .bin and .cue files by up to 50% without any loss in game data or quality.
Improves Organization: Merges multi-track .bin files (common in older PS1 dumps) into a single, clean file.
Playable Format: Unlike .zip or .7z archives, emulators like ePSXe can read CHD files directly, so you don't have to decompress them before playing. Using CHD in ePSXe
With the release of ePSXe 2.0.18 for Windows and recent Android updates (starting around version 2.0.16), CHD support is built into the core. CHD files - RetroPie Docs
The Evolution of Emulation: ePSXe and the CHD Standard For decades, the ePSXe (enhanced PSX emulator) stood as the gold standard for PlayStation 1 emulation, providing gamers a way to revisit classics like Final Fantasy VII and Metal Gear Solid on modern hardware. However, as the emulation scene matured, the traditional methods of storing games—primarily the bulky BIN/CUE format—began to feel dated. The recent introduction of CHD (Compressed Hunks of Data) support in ePSXe's December 2025 update marks a significant shift, bridging the gap between a legacy emulator and modern storage efficiency. The Storage Revolution: From BIN/CUE to CHD
Historically, ripping a PlayStation disc resulted in a messy array of multiple .bin files (for data and audio tracks) and a single .cue file to index them. This format was not only disorganized but also consumed massive amounts of storage space.
CHD Format: Originally developed for the MAME arcade emulator, CHD is a lossless compression format. It condenses those sprawling BIN/CUE sets into a single, highly compressed file without losing any original game data or audio quality.
Efficiency: A standard 456 MB BIN/CUE set can often be compressed down to roughly 348 MB in CHD format. For enthusiasts with hundreds of games, this results in gigabytes of saved space without sacrificing the "pixel-perfect" experience. Why the ePSXe Update Matters

ePSXe is a popular PlayStation emulator for PC that allows users to play PS1 games on their computers. One of the lesser-known features of ePSXe is its support for CHD (Compressed Hard Disk) files, which can be used to store and play PS1 games. In this article, we'll dive into the world of ePSXe CHD files and explore what they are, how to use them, and their benefits.
What are CHD files?
CHD files are a type of compressed file format that was originally developed for arcade games. They are used to store and compress game data, such as ROMs (Read-Only Memory) and disk images, into a single file. CHD files are commonly used in emulation to reduce the size of game data and make it easier to distribute.

Conclusion
ePSXe CHD files offer a convenient and efficient way to play PS1 games on your computer. With their compressed file size and improved compatibility, CHD files are a great option for gamers looking to play classic PS1 games. By following the steps outlined in this article, you can start using CHD files with ePSXe and enjoy your favorite PS1 games in a whole new way.
The transition from physical media to digital emulation has revolutionized how we preserve gaming history, and for the PlayStation 1 (PS1) emulator ePSXe, the adoption of CHD files represents a pinnacle of efficiency. CHD, or Compressed Hunks of Data, is a lossless compression format originally developed for the MAME project that has become a gold standard for disc-based emulation. While older formats like BIN/CUE or ISO often resulted in bloated file sizes and fragmented directories, CHD files offer a sophisticated solution that balances storage conservation with high-performance playback.
The primary appeal of the CHD format lies in its remarkable compression ratios without any loss of data integrity. PS1 games were stored on CD-ROMs with a capacity of roughly 650 to 700 megabytes, yet many titles only utilized a fraction of that space. Traditional disc images often preserved the "empty" padding, resulting in large files that quickly consumed hard drive space. CHD uses advanced compression algorithms to strip away this redundancy, frequently reducing the footprint of a game by 30% to 60% compared to a standard BIN/CUE set. For collectors maintaining hundreds of titles, this efficiency translates into hundreds of gigabytes of saved storage.
Beyond mere space savings, CHD files simplify library management through file consolidation. A single PS1 game in BIN/CUE format often consists of multiple files—one for the data track and several for Redbook audio tracks. Managing these can be cumbersome, and missing a single ".bin" file can lead to missing music or game crashes. A CHD file merges all these tracks into a single, cohesive container. This "one game, one file" approach makes organizing directories much cleaner and significantly reduces the likelihood of file corruption or pathing errors within the ePSXe interface.
Compatibility and performance remain the final hurdles for any compression format, and here, CHD excels within the ePSXe ecosystem. Modern versions of ePSXe and its associated plugins can read CHD files directly, meaning the emulator does not need to decompress the entire file into RAM before playing. Instead, it "extracts" data on the fly as the game requests it. This results in loading times that are virtually indistinguishable from uncompressed formats. Because the compression is lossless, the emulator receives the exact bit-for-bit data it would from an original disc, ensuring that game logic, graphics, and audio remain perfectly accurate to the original hardware experience.

In conclusion, utilizing CHD files with ePSXe is a transformative practice for retro gaming enthusiasts. By offering substantial space savings, streamlined file organization, and lossless performance, the format addresses the most common logistical pain points of disc-based emulation. As digital archives continue to grow, the CHD format stands as an essential tool for anyone looking to preserve the PS1's legendary library in the most efficient and reliable way possible.
chdman (comes with MAME or standalone tools like NamDHC)..chd file.chdman extractcd -i game.chd -o game.cue
.cue + .bin file. Load the .cue into ePSXe.✅ Works with all ePSXe versions.
❌ Takes up more disk space.
If you love ePSXe’s interface and plugin system, you can convert CHD files back to BIN/CUE whenever you need them.
You’ll need: chdman (included with MAME or standalone).
Command to decompress:
chdman extractcd -i "game.chd" -o "game.cue"
Pro tip: Keep your master library as CHD (to save hard drive space), but convert individual games to BIN/CUE only when you move them to your ePSXe folder.
No. As of the last stable version (ePSXe 2.0.5, released 2016), ePSXe cannot read CHD files directly. It expects:
