Help with pokemon sapphire sacred legends

Hi all i am making a rom hack of pokemon sapphire and i need help with the following things:

Battle scripting: I attempted to make a battle but when i tested it it just came up with a pink screen.

Inserting my custom world map: I'm unsure on how to insert my custom world map into the game.

Spriting: can someone please make a sprite for these two fakemons i have attached drawings of the fakemons to this post so you know what they look like.

Editing the credits: Can some1 tell me how i can edit the credits to my rom so i can include people who helped out with it in them.

Thanks

Sos guys I accidently clicked the post button before i attached th files ( slaps self round the face 40 times) so they are instead attached to dis post

Uhmm sorry dude but this is the game development section not the rom hacking section:S
