Guys, can you do me a favour? Try to download & run Wait 1.2 by TOYS: http://no-fragments.atari.org/no_fragme ... ait1_2.zip
on your SuperVidel Falcon. Doesn't matter whether with the drivers or just plain VGA, the important thing is to have the SuperVidel fitted.
Ideally if you could observe not only whether the demo has finished to the end but also whether you can see the output on both screens -- for me I see only Videl (VGA) output, DVI is totally black. When testing this, make sure you have cloning enabled in your SV.INF, if you are starting the demo from a SV resolution.
Other demos (which work) like my TBL ports, various other 060 demos work all right *and* have both outputs visible / mirrored. The only exception is DONT by DHS and guess what, it stops after a while as well (music continues, same as with Wait).
I'll try to fit my other SuperVidel just to be sure. I really don't believe this kind of bug could have been present from the beginning (i.e. not working with some special (?) demos) but who knows. The test above should clear my doubts.
