I don’t have an adapter to connect to AV3, if you can point me in the right direct i’ll get one to do some testing with.
I was thinking about this a little bit last night. I’m no expert at these things but the Neo Geo CD has a dedicated S-Video connection, do you think the fact that this connection is seperate could in some way have an effect on the sync strength of the AV port and if so could a crazy combo cable be used plugged into both the s-video and AV out ports on the Neo Geo CD wired to use the S-video as Sync? I think this would be a little bit like luma sync wouldn’t it? Obviously it’d be no good for other AES/MVS but it might be a fix for CD’s.
