3DS - Minor issues

[jpz-10]

I noticed the following things in the Nintendo 3DS Architecture analysis and wanted to report them:

1. The section 'Constructing the frame' may be misleading, as it says that the 3DS always renders three screens. My understanding is that this only happens in 3D mode, and that in 2D mode it renders two screens instead.

2. In sections 'Any other CPUs?' and 'Nostalgic rendering', the analysis refers to the Game Boy Advance as "Game Boy Advanced".

3. In section 'Nostalgic rendering', there is a typo: "...and then forwarded to the framebuffer, where..." should be "...and then forward it to the framebuffer, where...".

4. In section 'The ‘New’ enhancements', there is a typo: "With the New 3DS, the microSD can’t be replaced without taking the back cover is taken off.".
