The file Metal Gear Solid (Spain) (Disc 1) (Rev 1).chd refers to a specific digital revision of the Spanish-localized PlayStation 1 release. A "Rev 1" (Revision 1) typically serves as an official "patch" or updated version of the original retail disc (Rev 0/v1.0), containing bug fixes or minor content adjustments. Key Features of the Spanish Revision
Spanish Localization: This version features full Spanish voice acting and text, a notable part of the European PAL releases which included separate localized dubs for major territories.
Revision 1 Adjustments: While specific changelogs for PS1 revisions are rarely public, these updates generally addressed game-breaking bugs or technical glitches found in the initial launch. PAL Format Characteristics:
Runs at a lower framerate (50Hz) compared to the NTSC (60Hz) versions.
Difficulty-based torture rounds; specifically, the torture sequence is considered slightly easier on PAL due to the lower framerate allowing more time between button presses.
The intro cutscene "Sleeping late as usual, eh Snake?" is unskippable in this version. Technical File Details
CHD Format: This is a "Compressed Hunks of Data" file, often used in emulation to save space without losing data quality.
Disc 1 Content: This disc covers the initial portion of the game, including the iconic introduction and the first several boss encounters. To progress past the midpoint of the story, you will need to swap to Disc 2.
Saving: To save your progress in this version, you must contact Mei Ling via the Codec.

Unlike the NTSC (USA/Japan) versions, the Spanish PAL version features fully localized voice acting. Metal Gear Speedrunners Revision 1 Changes:
Revision 1 (v1.1) generally includes minor code optimizations. In some PlayStation titles, revisions also included updated demos or slight changes to anti-piracy measures. PAL Characteristics:
The game runs at 50Hz (standard for European PAL regions), which results in a slower framerate compared to the 60Hz NTSC versions. This affects gameplay elements like the "Torture Room" sequence, which is technically easier on PAL due to the slower input timing required. 4. Format Information: CHD
format is a lossless compression method used by emulators like DuckStation and RetroArch to save storage space without losing disc data (unlike lossy formats). Efficiency:
It reduces the original BIN/CUE size (~700MB) by roughly 30–40%. Compatibility:
CHD files support multi-track data, which is essential for PS1 games that use CD-DA (Compact Disc Digital Audio), though Metal Gear Solid primarily uses sequenced audio. For further archival details, the Internet Archive

This specific file refers to the Spanish-language release of the original Metal Gear Solid (1998) for the PlayStation 1, specifically the Revision 1 Technical Context CHD Format:
This is a "Compressed Hunks of Data" file, a popular lossless compression format used in emulation (like DuckStation) to save space compared to traditional pairs while keeping the data 100% intact. Revision 1 (Rev 1):
Unlike modern digital patches, PS1 revisions were "silent" updates issued on physical discs for later print runs. This version (SLES-01734) typically contains minor bug fixes and stability improvements over the launch version. Internet Archive Key Version Details
The Metal Gear Solid (Spain) (Disc 1) (Rev 1).chd is more than just a compressed game file. It’s a preservation milestone—a digitally archived piece of Spanish localization history, a bug-fixed snapshot from 1999, and a testament to how modern compression (CHD) can keep rare regional revisions alive. For MGS completionists and emulation enthusiasts alike, tracking down this specific CHD is akin to finding a hidden codec frequency: obscure, rewarding, and essential for the full picture.
To appreciate what this specific version offers, it is helpful to break down each part of the name:
Spain: This denotes the localized version for the Spanish market. Unlike the US release, this PAL version features a complete Spanish dub, with the voice of Solid Snake provided by Alfonso Vallés.
Disc 1: Metal Gear Solid was a cinematic experience spanning two physical CDs on the PlayStation 1. Disc 1 covers the game from Snake’s insertion at the Twin Lakes until the critical encounter with Sniper Wolf.
Rev 1 (Revision 1): This signifies a later pressing of the original disc. After a game's initial launch (v1.0), developers often released "Rev" copies to include official bug fixes or minor gameplay tweaks without marketing it as a new game.
CHD: 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)
The Spanish version of Metal Gear Solid is often celebrated for its high-quality voice acting, which was a rarity for international localizations at the time. Because it is a PAL region game, it natively runs at 50Hz (compared to the 60Hz NTSC version), which can slightly change the game's timing and speed. Some players find certain challenges, like the infamous torture sequence, marginally easier due to the lower framerate of the PAL version. Why Use the CHD Format? Given the specifics, here are some points to consider:
Converting a PS1 game to CHD is a popular choice for retro enthusiasts using devices like the Miyoo Mini or software like RetroArch.
Storage Efficiency: CHD files can be significantly smaller than standard disc images, which is vital when managing large libraries on SD cards.
Single File Management: Instead of multiple files per disc, you have one clean file, which reduces clutter in your ROM directory.
Lossless Quality: Unlike some compression methods that can degrade audio or video, CHD preserves everything exactly as it was on the original Spanish disc. Tips for Multi-Disc Management
Since Metal Gear Solid requires a disc swap halfway through the story, playing with CHD files on an emulator requires a specific setup to ensure a smooth transition:
This is where the detective work begins. Sony’s mastering process involved multiple revisions (Rev 0, Rev 1, Rev 2, etc.). A "Rev 1" indicates a second pressing or a bug-fixed version after the gold master. Changes can include:
For Metal Gear Solid, Rev 1 in Spain might address a specific localization error where a guard’s alert phrase was mistranslated. Collectors obsess over Rev 1 because it is often the most stable, yet least common, pressing.

In the vast ecosystem of video game preservation, few objects generate as much quiet fascination among collectors and digital archivists as the seemingly mundane disc image file. At first glance, “Metal Gear Solid Spain Disc 1 Rev 1.chd” appears to be a dry technical descriptor: a reference to Hideo Kojima’s 1998 masterpiece, its Spanish regional release, a revision number, and a compressed file format. Yet, for connoisseurs of PlayStation history and digital preservation, this specific file represents a critical junction where language, censorship, hardware limitations, and the art of salvage converge.
Critical. While most preservation dumps focus on "full sets" (both discs), "Disc 1" specific dumps are often sought after because Disc 1 of Metal Gear Solid contains unique anti-piracy triggers (e.g., the famous "Psycho Mantis memory card read" and the "Codec frequency on the CD case back"). Variations in Disc 1 are more common than Disc 2.
