If I understood your question correctly you just want to know what the met table should look like for the Nidoran. Below is an image for my Trapinch met information, but it is identical to what a a Nidoran met information would be. Also, if you're making the Pokemon for a gen 5 game make sure that the extra bytes 0x42 is set to 1. If it is for a gen 6 or 7 game all of the extra bytes are 0.
