NeoGeo CD emulator have been updated recently. Changes:
- Sound sample rate can only be 44 Khz in neoraine because of the audio cd tracks, so the sound options don't allow to change this.
- When stopping sound emulation in the middle of a game the sound now stops immediately.
- See raine changelog for version 0.51.0 for changes not specific to neoraine (gui, console, video...).
