unanswered Pokémon Black & White - Editing Overworld's Trainer Battle

[Oxnite]

Hello all,

Each overworld in a/1/2/5 (for BW) has a certain script, e.g.:

03 00 0C 00 0A 00 01 00 00 00 B9 0B 02 00 02 00 00 00 00 00 00 00 00 00 05 00 05 00 F6 02 79 02 00 00 00 00

...which determines the overworld sprite, movement, range of sight, map location, etc.

Now, for standard Trainer Battles with eyesight, their scripts could be, for example B9 0B (as in the above example).

Where can I find these scripts?

And, in particular, can I use the base of a Double Battle trainer script to get the ''at least two Pokémon in party-check'' script for other Trainers?

This is obviously something I could find somewhere on this forum but I swear that I have searched for more than half an hour. Excuse my search skills.

Thank you very much!
