Thank you so much! I just downloaded it and it seems to work fine, though I only tested it for a few minutes. I've been dreading reverting to Ep. 15 just to change the weather since I've been stuck on heavy rain for more than a month (Can't use Fire types).
For anyone wondering how, the download comes with a 'Scripts' file. Put it in place of the Scripts file in the Pokemon Reborn Data folder, though keep the old one just in case.
Also I'm not sure what you mean by the other things.
I'll pass on getting multiple starters, assuming that's what you mean; Having a Snivy,
