Wal-Mart had the XL at this price two weeks ago and I jumped on it. Truly the best way to play DS games. I assumed my 3DS would be the way to go, but it's back compat is a huge letdown.

Really?  I haven't had any trouble.  What sort of issues are you seeing?

It applies a filter that makes it a blurry mess... I am being a bit picky, but I really wish you could turn that off. The tiny scale option is not really a good alternative, either.

It isn't a filter, it's due to image scaling. The 3DS has a higher resolution than the DS, so DS games are stretched out to fit the 3DS screens. There's no way to get around that because the two resolutions don't match up; think of it as watching SD content on an HDTV. The "tiny scale" option is the DS's original resolution.

Don't try to use all of this "logic" and "math."  This is the internet and I am opinionated about something unimportant!

Seriously, though, I know it's their way to make the resolutions work out... it just seems like the upscaling could be done with a different technique, but I don't know anything about how that's done.  I'll just sit here content with my affordably priced DSi XL and stop complaining.

Doing my research for the Final Fantasy Retrospective, I keep coming across screen grabs of the NES and SNES games in super high resolution. I'm assuming that these are taken from someone playing on a ROM with the settings tweaked. My question is-why can't we get this on our systems? I certainly wouldn't mind playing 8 and 16 bit games in high resolution at the original aspect ratio.
