You want the "new" set. Here is the technical workflow used by archivers today.
Redump provides BIN/CUE (with separate tracks for audio). A 1G1R set should be converted for use:
The term "Redump" refers to a community project dedicated to dumping (copying) disc-based game data with extreme precision. Unlike older, sloppy rips that often removed dummy data or audio tracks to save space, Redump validates that the ISO (or BIN/CUE) is an exact 1:1 copy of the original physical disc. 1g1r redump snk neo geo cd new
For the Neo Geo CD, this is critical. The system was known for lengthy load times, and many "bad" dumps floating around the internet for decades are missing CDDA audio tracks or have corrupted data tracks. A Redump set ensures you are playing the game exactly as it appeared on the original hardware, including the correct region, copy protection, and file structure.
Redump is a collaborative community project dedicated to creating perfect, verifiable disc images of commercial video game media. For the Neo Geo CD (including the Front-Loader, Top-Loader, and CDZ models), Redump provides the definitive "source" set. You want the "new" set
Before we dive into the Neo Geo CD specifically, let's break down the keyword components.
This is the crucial filter. A full Redump set of Neo Geo CD contains every single disc ever released worldwide. That often means: 1G1R solves this by keeping only one version per game
1G1R solves this by keeping only one version per game. The goal is a complete library of unique titles, not every redundant copy.
The "new" preservation standard for Neo Geo CD is CHD (Compressed Hunks of Data). CHD reduces the 15GB full set down to ~5GB with zero data loss. All modern emulators (RetroArch, NeoCD, MAME) support CHD.
