Here's what you need to do:
1. Try and insert the picture in what offset you find in a document there. If it works, you're done. If not, actually look in the document, and find the offset.
2. Stop being a newbie.
Seriously, don't ask me this again, or I'll just block you. You're cluttering my profile, and asking me questions, expecting me to take time out of my life just because you're too lazy.
Okay, fine, seeing as you didn't argue and act like an ass, I can tell you some information. I know where the backsprite is, but why do you need to overwrite it? I though you were working on a RUBY hack.
Really, you're calling me a nerd? Anyway, I suppose you said that you were sorry, so we can move on. However, let me correct several things you said:
1. Hacking Silver is MUCH harder than Ruby. You really have no idea. I've hacked both versions, and you don't even need to use a hex editor to hack Ruby. If you want to get in an arguement about this, go ahead, I'm right.
2. Why decrease the look of graphics on a Advanced Generation game? Also, what's the point of it? You can just play it with better graphics on the SAME system.
3. AGPIX only works for Gold and Silver, not Ruby. Why would you even need it for your so-called hack?
EDIT: Also, why steal the name of my hack? You could at least be a little original....
