I think Andrew posted a couple more notBD binaries in the AtariAge
forums but that's about it. No-one besides him is currently using
this bankswitching format, and I'm not sure if Armin ever wrote
a test binary for himself when he designed the Kroko Cart.

z26 supports interlacing only in those video modes that have every
other scanline blank to simulate a TV display (modes 3, 4 and 5).
In these modes we just display the first VCS frame in the odd lines
and the second frame in the even lines to simulate the higher
resolution with interlacing.
