I want to use a sprite in the game that is greater then 64x64, is there a way to use the sprite without having to manage multiple oams?

You could always dedicate a whole background.

you can also use the 3d system for sprites, if you know how.

I cant seem to draw the sprite on the screen since the maximun sprite size is 64x64

OAM Sprite sizes are limited to 64x64. As replied before me, use the BG or the 3d engine.

Here:

Cglsprite and Cgl2d classes.

Ok, thats one option, would it also be possible to use grit maps for sprites? the sprite i want to use is only about 120x80
