Report Title: Creation and Verification of CHD Format for Metal Gear Solid (Spain, Disc 1)

Date: [Current Date – e.g., 2026-04-19] System: Target – Sony PlayStation (PS1) via emulation (e.g., DuckStation, RetroArch, PCSX-ReARMed) Source Material: Metal Gear Solid (Spain) – Disco 1 (CD-ROM) – Original or verified 1:1 raw dump (BIN/CUE or CCD/IMG) metal gear solid spain disc 1chd work

Issue 2: "Freezes during the DARPA Chief scene"

• Cause: A bad sector conversion. The DARPA Chief’s death scene uses a specific streaming audio buffer. If the CHD’s hunk size is misaligned, the audio buffer underruns.
• Fix: Recreate the CHD using the --hunk 4096 flag. DuckStation and PSX cores often need 4096-byte hunks for this title.

2. Why CHD Format?

• Saves space compared to BIN/CUE
• Works perfectly in modern emulators (DuckStation, RetroArch, ePSXe with CHD plugin)
• Single file per disc, no multiple tracks to manage

Common Failure Signs:

• Black screen after saving Meryl at the tank hangar.
• Codec calls have no voice audio (only subtitles).
• The game restarts when climbing the ladder to the chopper.
