B/W 1 crashes with edited a/0/7/9.narc

[Deltagaming025]

So, I have been trying to make a pokemon black ROM hack where you play as brendan, and I've gotten the battle back sprite to work, but when I inject my edited overworld sprites into a/0/7/9.narc, I start the game, it gives me the pokemon logo, fades to black, and stays black. Nothing will load. I've included the sprites i'm using along with the NARC file. Please tell me what I've done wrong!

EDIT: I got the game to load this time, but now all of the menu options appear without any text, and selecting anything causes it to freeze on a black screen. Also just tried it with White 1 (Not volt white) And it freezes again on a black screen after the pokemon logo. It seems that there are only issues when i inject a/0/7/9.

Oh I forgot to mention I'm using pokemon Blaze Black as a base. I tried it with the normal black, but the sprite just stays the same even though the sprite is modified.
