is it against rules for me to make a code request for pickits?

it is not a 3rd party program its just text in a file. I would see no reason why not but I do like to follow the rules

what would be the correct forum to post it under if allowed?

Won't be allowed. If you think of it, all programs are texts at first. It's still in the family of " third party" i think.

It falls under the category of 3rd party programs; which the rules clearly state that anything referring to the nature of 3rd party programs cannot be discussed.
So yes, asking for scripts is against the rules.

It's not allowed. Anything that alters the original game files falls under piracy.
