Sorry, I didn't know you asked since you didn't reply. If you do want to use the mod, replace the 'script.rxdata' that is in the Data folder of Reborn with the new 'script' file. The other file goes in the same place as the Reborn game. From there, everything is in the Pokegear. However, I still can't confirm if this works on event mons. It does help reduce weather lag on my computer quickly though.
No problem. Thank you for putting in the time to do experimentation/research into the problem.
