Are you going to merge that before release?
Yes, FDC major changes are one of the point of the release.
so I think it's an FDC problem and both demos
use the same loading routines.
According to compatibility list, they worked already with Hatari <v1.0.
And I remember them working also few years ago. But --slowfdc option
doesn't affect them.
That was because FDC emulation before was really minimal and didn't
emulate a lot of things, just reading sectors and discarding most of the
rest. It was enough for this case, but unusable when right timings are
required for example.
Oxygene's sprite record gives also double bus error at start:

Confirmed, works with my improved FDC. I think those 3 demos are using
Leonard's loader routine
Paolo's Panic:

Shows pretty horrible flicker, which I don't remember
happening when I tried it earlier (in 2008 I think,
based on file timestamp :)).
Yes, there must be a regression in some overscan emulation, should be
easy to fix.
