I've written a small program that captures in HI240 and converts to
YCbCr 4:2:0. The output is either PGM as generated by mpeg2dec or Y4M
as expected by the mjpegtools. The HI240 to RGB formula is from
xawdecode.
You can find it at

While skipping through the Fusion 878A datasheet, I found a sentence
which made me realize that the problems associated with switching from
one GNT to another in idle state are not limited to IDSEL stepping.
Inserting a cycle with all GNTs deasserted is required because a device
parked on an idle bus must drive the AD and C/BE# lines. This is not
correctly modeled in the simulation.
