Do you think that it possible to simulate long software reset (4 seconds) for rom switcher?

It's not.

It's the industry standard amiga reset code. It was used before Kickstart 2.x and later ROMs.

Hard reset is just the abovementioned code with trashing of the execbase pointer (or execbase itself). For example: move.l #-1,(4).w

The idea is to make the OS forget the old execbase so that you get rid of all memory resident stuff.

Thus, the difference is in the software. It doesn't generate any longer reset.
