i think is a WHDLoad's bug.

indeed i use WHDLF_EmulDivZero flag, normally WHDLoad would not leave on error message and ignore this exception.

same problem with Twylyte and Hoversprint (soon released)

I asked Bert (WEPL) about this.

I'm waiting for his answer.

see AUTODOC:
WHDLF_EmulDivZero / WHDLB_EmulDivZero
                   This flag has an effect only if the VBR is moved by WHDLoad
                   (i.e. the machine is at least a 68010 and the tooltype
                   NoVBRMove is not set).
                   If the flag is set all division by zero exceptions are
                   emulated by the exception handler inside WHDLoad. I.e. the
                   handler checks if the vector ($14) is initialized and if
                   the routine to which the vector points to will be called by
                   WHDLoad.
                   This flag has precedence over the flag NoDivZero.

@CFOU

No I have only tested with 68010 with Winaue.

Is it possible fix the "Integer Divide by Zero" issue with the other games as well?
