Historically, downloading PlayStation games meant dealing with complex .bin and .cue files. Often, a single disc would output dozens of .bin files for individual audio tracks. Choosing a .chd version offers massive advantages:
Metal Gear Solid was released with several revisions throughout its lifespan to fix bugs and improve stability.
: This is a modern, lossless compression format ("Compressed Hunks of Data") designed to reduce file size without losing any original game data. It is the preferred format for CD-based systems on modern emulators because it merges the old .bin and .cue files into a single, space-efficient file. The Spanish Localization (PAL) metal gear solid spain disc 1 rev 1chd
Denotes the specific regional localization. In the late 1990s, games were heavily localized for European markets (PAL region) to include specific text and voice acting.
Spain, as a major European market, received a specific pressing. The “Rev 1” designation is crucial. In manufacturing, “Revision 1” indicates a post-launch correction—perhaps addressing a game-breaking bug, adjusting subtitles, or modifying content to meet Spanish ratings board requirements. Unlike later “Platinum” or “Greatest Hits” reprints, a Rev 1 disc is often a hidden patch, released quietly to distributors without fanfare. : This is a modern, lossless compression format
Organizations like catalog these hashes. A perfect rip of Metal Gear Solid (Spain) (Disc 1) (Rev 1) , before being converted to CHD, will match specific MD5 or SHA-1 signatures assigned to Serial ID SLES-01508 .
Load the .m3u file into your emulator instead of the individual .chd files. When the game prompts you to change discs, use your emulator's quick menu to virtually open the disc tray, cycle to Disc 2, and close the tray. Your save data will carry over instantly.
