Many "highly compressed" links are clickbait designed to distribute viruses, trojans, or adware. The download is often an .exe file or a password-protected archive that installs harmful software on your PC instead of a game. 2. Stripped and Ripped Content
You do not need to risk your PC's health downloading broken files from untrusted sites. The PCSX2 emulator natively supports compressed file formats. You can take your own clean, full-sized ISOs and compress them safely yourself. The two best formats for this are and CSO . Why CHD is the Current King of PCSX2 Compression
The software looks for repeating patterns of data and indexes them efficiently. pcsx2 games highly compressed work

Before diving into the compression process, it is crucial to understand which file formats are natively compatible with the emulator. PCSX2 has evolved significantly over the years. While older versions (such as the stable 1.4 and 1.6 builds) offered limited support for compressed images, the latest nightly (dev) builds have expanded compatibility to include several modern compression standards. Specifically, as of version 1.7.0 and later, PCSX2 natively supports the following formats for direct loading: . For the purpose of space saving, we will focus on the three most relevant compressed formats: CHD, CSO, and GZ.
Standard compression algorithms like or RAR can significantly reduce the size of a PS2 ISO. This works incredibly well for games that contain a lot of "dummy data" (blank space used to fill up a physical DVD). For example, a game like LEGO Star Wars might shrink from 4 GB down to 1.2 GB because the actual game assets are small, and the rest was just filler. 2. Destructive Compression (Ripping)
