Hi, liuyanghejerry, nice to meet you, I know you is a professional rom Chinese hacker, I'm Chinese too, but why your Chinese hacking tutorial forum can't be displayed the webpage, this http://poketb.com/bbs/thread-15264-1-1.html
If you having other Chinese hacking forum can PM/VM me? And can you do a JPAN's Fire Red Engine translation? If you already quit hacking, sorry for bother you...
Well I think this could be an alternate solution for your titlescreen
I don't know if you already considered doing it this way...
Your titlescreen is going to be separated into 2 parts:
The one with the bulbasaur, squirtle, and charmander
and the one with the people, name and the map.
So, my idea is to insert the first part (the one with the starters) in the very first screen, I mean the one that is something like this:
2004 Pokémon 1995-2004Nintendo 1995-2004 Creatures inc. 1995-2004 GAME FREAK inc.
So you insert your images with the black screen.
And the rest, you can insert it in the real titlescreen.
But yeah.. I wish someone with skills like you made a titlescreen changer tool, it could help some N00b hackers.
