Hey , can anyone help me with a subtle problem I'm having with
switches?(this is a 64Y variant BTW- with JSW1 design sensibilities
and 64engine features) Technically the switches work ace! But
I've noticed that when The Willy sprite collides with an inked pixel
of a switch graphic, the whole row of pixels for the switch is
obliterated. Is there anyway that willy's sprite can merge with the
graphic as in Manic Miner and JSW2 rather than wipe out the whole
row of pixels?

No. It's because switches in JSW64 are guardians and use
guardian-based collision detection. When the switch detects a
collision, it stops drawing. I could probably fix it if there were
more spare bytes available, but there aren't so I can't.
