Sometime ago I converted a set of NeoGeo CD games to .CHD(using chdman.exe) and it works somewhat ok, but some sound errors occurs in games like Fatal Fury series and many others, but now I just discovered that many of these errors dont occur with pure bin+wav .cue dumps without compression in game files. It Is a shame because I really needed the saved space, but had no choice but to delete all my CHDs and replace with raw bin_wav NGCD dumps to get a better audio in game.
Games tested with the new fullset redumps from archive.org neocd-sd-loader.
