Had a look at this issue -
http://code.google.com/p/mupen64plus/issues/detail?id=553

Implemented the proposed fix on my own and that got rid of the spurious
crashes for me.  BTW - Mischief Makers is another game that reports
this warning "two events of same type interrupt queue". Anyway,
returning when that happens gets rid of the crashes in PD.

littleguy note: You might need to delete any pre-existing .eep and .mpk
files from the SlotSaves directory and reset the game the first time
you run with this fix.  More discussion here:
