I checked Checkpoint's Second Reality STF demo
and while it works with OldUAE CPU core and if
I use "--cpu-exact no" for WinUAE CPU core, it
doesn't work with exact WinUAE CPU core:

(Bus errors right at beginning.)


When using WinUAE CPU in CE mode, interrupts (in that case FDC interrupt) were not always correctly handled.

After discussing with Tony, this is because the way interrupts are handled at the moment at Hatari level is not how WinUAE's CE mode expects the ipl signal to be updated.

A fix has been added to keep it working anyway, but integration of CE mode in Hatari is still a work in progress.

With this, the demo runs completely (that's also because it doesn't use too many effect like plasma or overscan which are not correct yet in all cases in CE mode)
