First thing to do with P96 is choose attach to board from top of its screen.
Here, it is german, but it show to do it.

Thanks - that helped a lot. However, when I run Picasso96Mode, it opens with "not attached: Village-64" in the Settings panel. I followed the video and dragged a new setting into the Seetings panel, then went to the right-click "Attach setting to" drop-down menu. But the drop-down in the video lists three items, "No Board, Board 0, and Board 1". Mine only has "No board".
But when I do showconfig, it has
Board (Viona Development): Prod=2193/1($891/$1) (@$0 2meg)in it, so at least
that seems to think a Picasso board is there.
So something is screwy here. Say, am I supposed to have a "spectrum.device" or some similar name somewhere? Because I looked in SYS:Devs and see nothing at all like that there.
UPDATE:
Answering my own question, I see a thread here
https://forum.amiga.org/index.php?topic=70917.90 where someone says "Went back thru all my procedure.... had the GBAPII++.card file in Libs:
Should be in LIBS:Picasso96/"
So I looked in SYS:Libs/Picasso96 and sure enough, there *is* a Spectrum.card file there. But still nothing in the Picasso96Prefs drop-down.
