How to Fix the "dl-1425.bin NOT FOUND" Error in MAME If you're a retro gaming enthusiast, there is nothing more frustrating than firing up a classic CPS2 game (like Street Fighter Alpha 3 or Marvel vs. Capcom ) only to be greeted by a "Required Files Missing" error.

The Problem

: Users often encounter a "Required ROM/disk images for the selected system are missing" error because their ROM set is outdated or missing the specific qsound_hle.zip archive. Technical Background

1. Identify your ROM version: dl1425.bin has several revisions (e.g., dl1425.bin for CPS-1 vs dl-1425.bin for CPS-2). Use a ROM manager like ClrMAMEPro or ROMVault.
2. Locate a merged ROM set: Look for a MAME 0.251 or newer "merged" set that includes the QSound parent ROMs. The file is often inside qsound.zip or cps1.zip.
3. Correct SHA-1 Hash: For most Capcom games, the correct hash is:
   dl1425.bin → SHA-1: e3a5ec54c53ad17bf5cbb1d9cde622d1b94f9e9c
   Verify any downloaded file matches this to avoid corruption.
