You're not working on this rom alone, are you? Kudos to you for your hard work and dedication.
EDIT: They're times when [so far] the Professor calls you by your rivals name [in my case it'd be Barry]. And they're other times when you're called by punctuation marks [!,?,etc.]
I'm not far in the game, but from where I am the grass seems to be buggy and "flashes" if you will.
Ah, thanks a lot. Actually, I AM working on this Rom by my own, and I really love to do it.
Yep, I know about that bug. It's a pity, but I'll try to change it as soon as possible.
And, what? Flashing / buggy grass?
