Hi all,


Electric night demo doesn't run with the latest hatari version.

It starts with the VHS K7 effect, then the 1st Dune logo appears and then it freezes before the first colored tore effect.

I've bissected it and it is broken since this patch :


25833053487457424fdd4bb893c8afb8cbd74af0 is the first bad commit

    When changing GPIP bits in the MFP, we must use MFP_GPIP_Set_Line_Input instead of MFP_InputOnChannel

Is it the same for you ?

Hi

I see the same problem ; as you have the code for this demo, do you see what part in the code could cause this ? I think it's related to the sound interrupt hreq, which IIRC is not completely emulated in falcon mode. It's possible the change I made (which should be valid) are exposing some limitation in hreq emulation.
