No.00453 Tafoid Administrator Mar 28, 2008, 14:10	I'll be honest here - I don't notice a difference between 0.123 MAME and 0.124 MAME as regards to the Neo-Geo sound. I ran both with headphones and listened - they both seemed to me as the same and quite spread out between left and right. Tried mslugx, pbobblen, crsword - all seemed to behave the same and as expected. If you can gave a specific example of a game not working correctly and a -wavwrite recording of the emulation proving this - maybe we can help. I know in the past, some on-board sound environments that 'fake' the 3D sound (c-media for example) - I know I had some odd problems with sound at one time until I disabled the "XEAR 3D" mode. Can anyone else confirm or deny this report?
