Ah, I got a Female Nidoran from the Viridian Forest Escape Rope glitch with one of the trainer before Mt Moon.
Then with EXP underflow, it turned into a lv100 Nidorina, then a lv100 Nidoqueen with a Moon Stone.
It had Special of 184 and I was able to encounter the MissingNo Ghost and clone my items.
Thanks a bunch for all your help, man! =)
