Desaturation isn't the proper word. The colors look the same as they did on the GBA. The image has just been darkened as if played on a lower brightness setting. They also have two options- original resolution or stretched. And unless you'd like your image to appear all jagged with uneven pixels (the scaling isn't 2x the original, so some things are going to look awkwardly scaled), the blur filter is basically required to make the games look at all decent stretched.
The motion blur is the only real problem. And how bad it is is completely subjective. You also covered nothing about being able to use the analog slide pad, or that X also functions as an alternate button for Y (alleviating any control gripes people might have with how buttons are positions). And of course you never mention that the games can be booted unstretched in original resolution.
Saying they're unplayable is a laughable statement too. There's nothing unplayable about these games at all.
