WTF is wrong with this GBA code

[TheDarkJay]

I'm taking a course in GBA programming, and decided to try to get it to show pixels on the screen.

ERRORS ALERT!!!! I get over loaded with errors and i don't know what i am doing wrong.

Code:

Line 148 is missing enclosing parenthesis.

Might be other errors, but that's the only one that stood out when I scanned over it.
