Games like Final Fantasy VII , Metal Gear Solid , or Chrono Cross span across multiple discs. When these are converted to CHD, you will get individual files like Game (Disc 1).chd and Game (Disc 2).chd . To ensure seamless disc swapping within your emulator: Create a plain text file next to your game files.
Converting your game library is straightforward, using a tool called chdman that comes with MAME.
Because CHD files represent a single disc, games like Final Fantasy VII or Metal Gear Solid will result in multiple CHD files (e.g., Game (Disc 1).chd , Game (Disc 2).chd ).
The PlayStation 1 (PS1) remains one of the most iconic video game consoles of all time, housing a massive library of defining titles like Final Fantasy VII , Metal Gear Solid , and Resident Evil . However, if you are building a digital collection for emulation, you quickly run into a major roadblock: storage space. chd psx roms
To convert your entire folder of hundreds of games:
Converting your existing PSX library to CHD is incredibly simple and completely free. The most efficient tool for the job is (CHD Manager), a command-line tool bundled with MAME.
Update your emulator. Older builds of ePSXe or RetroArch do not support CHD. Switch to DuckStation. Games like Final Fantasy VII , Metal Gear
In the context of the PlayStation 1 (PSX), a is a single-file archive that contains all the data from a PSX game disc. Unlike the standard .bin/.cue or .iso formats, which often require multiple files (especially for multi-track audio games), a CHD consolidates everything into one file.
Virtually every major modern PlayStation 1 emulator natively supports CHD files without requiring plug-ins or workarounds.
Emulators read compressed data faster, reducing loading times on slower storage drives. Converting your game library is straightforward, using a
Almost every major modern PlayStation 1 emulator supports CHD files right out of the box. You do not need to install extra plugins to run them.

Save the file in the same folder as the games, naming it Final Fantasy VII.m3u .
: Despite the high compression, CHD files are designed for efficient random access. In practice, emulators can load and play CHD files without noticeable slowdowns, loading delays, or bugs. The independent compression of each "hunk" effectively eliminates performance bottlenecks that plagued older compression methods like CSO.
