Renewal item drops, questions, etc.

[Elenaya]

Does anyone happen to know how to figure out things via the KRO/iRO for monster drop rate?

Doddler has his database for renewal drops; however, it's unfinished to a point according to him, so I was wondering if anyone knew where to look for information in the GRF or somewhere in the client itself for drop rates?  I've never done something like that, but I enjoy fiddling around things.

If this is in the incorrect area of the forums, feel free to move it.

Thanks for any replys!

Drops are specified in emulator settings (eathena\db\mob_db.txt or txt version db.mob_db.dropxxx for sql one)
