Any sighting of the elusive Big Cat?

open the start menu and type in regedit. That opens the registry. Then you just have to find the maplestory folder and under siFieldID should give you the Id of the map. There are a total of 10 of them 00 to 01

Ah, many thanks. I've used it to figure out that I'm in map 08 (is it the last two digits?), I think. Okay, I'll keep that in mind.

EDIT: On a side note, I'm beginning to notice that some channels have a curious lack of a black jaguar on the top-left platform. Is that where Jaira usually spawns?

I've went around killing regular black jaguars in other channels that do have a black jaguar on the top-left platform, but another black jaguar usually immediately takes their place. Not in the case of a channel where the black jaguar is completely absent. I wonder if it means anything?

EDIT 2: Killed other jaguars, figured out that the above observation doesn't mean anything.
