Following up to my own message, I solved the problem!
It turns out that Air-Sea battle reads the images of the collision
registers at $00/$01, as opposed to $30/$31. It looks like the SC
interferes with the mapping of the read-registers, maybe because
they overlap the write-registers there?
At any rate, patching the code to use the images at $3x makes it
work on the supercharger.
Specifically for Air-Sea Battle,
offset $00b9: $00->$30
offset $00bd: $01->$31
offset $004a: $00->$30
I guess some reads from the range $00-2f are being redirected in
some way? Hmm...this is a darned good reason to use a version
of VCS.H with the read addresses >= $30.
At least it shouldn't be too hard to patch the other games if there's
a rerelease of WTW.
