Really nice work! Perfect for use right away as mock GB / controller images. However, if you wish to use them to create a 'fake' GB display for a game then you'll need to put in some serious work in Photoshop to prepare them first - aligning the layers, cutting out the labels, etc. The components in the PSD are just flat images with very few layers (the screen, for example, is all literally just one layer with a drop shadow, and not a Smart Layer either) - this isn't a complaint, as the quality is really high and they are completely free! Just be aware in advance that you've got to put in some real effort to make these useable in a game.
