There is no tool for inserting a title screen (as far as I know). You should look more closely at the tutorial section, though, because there is definitely more than one tutorial, and if you patch them together changing the title screen won't be too hard
2. Does anyone know how to change the events that happen if you black out?
3. Does anyone know how to stop the PC from healing your Pokemon when you deposit them?
Thanks to anyone who can answer these.
1). Search for it in A-Text and change it.
2). No clue.
3). I don't know for sure, but I would guess that that probably involves ASM hacking.
