: Many PSX discs were filled with "garbage data" to push actual game files to the outer edge of the disc for faster reading. Compression tools like 7-Zip or KGB Archiver could identify this useless data and shrink a 600MB ISO down to a few dozen megabytes. The Legend of KGB Archiver
Highly compressed PSX (PlayStation 1) games refer to digital disc images that have been processed to reduce their file size for easier storage and distribution. While a standard PS1 CD-ROM can hold up to 650–700 MB of data, many games contain significant "dummy data" (padding) or uncompressed audio and video files that can be shrunken without losing gameplay quality. 💿 Common Compression Formats psx games highly compressed

Developers often replace large cinematic files with tiny "dummy" files. This can shrink a game like Final Fantasy VII significantly, but you lose all the story cutscenes. Audio Ripping: While a standard PS1 CD-ROM can hold up

A format that strips out error-correction data from a CD image to save space. These files must be "un-ecm'd" before they can be played in most emulators. The "Ultra-Compressed" Method (Stripping)
There are two primary modern standards used for PSX game compression. Both are widely supported by popular emulators like DuckStation, RetroArch (PCSX ReARMed, Beetle PSX), and ePSXe. Best Use Case Key Features Compressed Hunks of Data General emulation & preservation
