: Known for efficient use of the PS1 hardware; even compressed, the tight platforming remains "pure". Metal Gear Solid

The PS1, with its limited hardware capabilities, was particularly affected by these compressions. Many PS1 games featured audio and video that were already pushing the limits of the console's capabilities. When highly compressed, these elements became severely degraded, often to the point of being unrecognizable.

"Fixed" means the game has been properly converted to a compressed format without losing essential audio tracks (CDDA) or data, preventing games from freezing or losing sound. Using CHDMAN (The Gold Standard)

The PlayStation 1 (PS1) is one of the most iconic gaming consoles of all time, with a vast library of classic games that still hold up today. However, for those looking to revisit their childhood memories or experience these games for the first time, there's often a significant hurdle: highly compressed games. In this article, we'll explore the world of PS1 highly compressed games, the issues they pose, and most importantly, provide a comprehensive guide on how to fix them.

Modern "fixed" highly compressed games typically use format, which is the gold standard for PS1 emulation. Unlike older "RIP" versions that broke the game, CHD offers lossless compression that maintains 100% of the game data while reducing file size by roughly 30–50%.

Most audio issues with CHD-compressed games stem from using an older version of chdman . The solution is straightforward:

| Problem | Likely Cause | Quick Fix | |---------|--------------|------------| | Audio crackling/stuttering | CPU overload or timing issues | Set CPU governor to performance; adjust Max Timing Skew to 0.000 | | Game won’t load at all | Corrupted compression or unsupported format | Recompress with CHDMAN; switch emulator core | | Music plays at wrong time | CHD audio track offset | Update emulator; recompress with FLAC | | Multi-disc swap fails | Individual disc files not linked | Use PBP with merged discs or M3U playlist | | Graphical glitches | Plugin or core incompatibility | Switch GPU plugin; change core to Beetle PSX | | Random crashes | High compression level | Recompress at level 5–7 instead of 8–9 | | Slow performance | Insufficient hardware | Lower compression level; disable VSync |
