Well, I'm actually making some progress, I have the script ready for when you enter the map and all that stuff.
But I'm still stuck at the part where you get the pichu egg

I just can't seem to give it.
And also "giveegg PICHU" doesn't work for some reason, well I'l figure it out.
And another thing, what do you want the voice to say?
I forgot to ask it but I actually don't know.
Anyways I will have it finished around tomorrow.
EDIT: Hey anonymous those sketches look really good :D
And about ips patching:
Get lunar ips (just download it from the internet)
And then open it and it will say create ips and will guide you through the steps :D
