No.00375 Haze Senior Tester Mar 24, 2008, 12:24	I've changed this from NeoGeo specific to YM2203, and marked it as critical. I can't test myself, but multiple sources are saying it's an issue, so it probably is.
No.00380 Tafoid Administrator Mar 24, 2008, 14:14	Neo-Geo is a YM2610, not YM2203 (at least - according to my information). Adjusted report. Before making any more bug reports for missing/incomplete sound, make sure the sound processor is not a YM2610 or YM2610B. If it is, it's covered by this report. If there are indeed YM2203/AY-3-8910a problems, that should be posted in another all-inclusive report for that chip.
