You can usually tell by looking. Most 1st-party games were in 8:8:8, and the 6:6:6 games (prince of persia, RE4) are usually very obvious.
But you'll play VC games...does that include N64 titles? Do you still play Gamecube, Xbox or PS2 games at all?
Most people on this board (myself included) are disappointed with the choices Nintendo made regarding Wii's silicon, but I also think that most of us do not equate "modestly improved" with "ruined." Prime 3 looks better than either of the previous games, just not as much better as most of us would have liked. Saying it's "ruined" is just blustering.
The DS is faster and has more RAM than the PS1, I thought. I think there are a couple features the DS has that the PS1 didn't, like Z-buffering. And I don't know if you noticed, but 2D games were on the GBA before the DS came out, so it's a definite improvement.

The max size of a DS game is less than 1/4 the size a ps1 game can be. ~128MB (i.e. ~1Gb) vs ~650 MB. Shorter games, lower quality video codecs, lower quality and less audio. Although I guess one could argue that PoR's synth music was almost as much of a geniune aural pleasure to some people as much as SotN's music was.
The PS1, and even the genesis run at a higher res than the DS, and the DS is hardly an improvement over the GBA, in that area.
The DS has only an 18 bit palette; the saturn, ps1, jaguar, and 3do all have 24 bit palettes. I guess one could argue that the other systems i mentioned usually don't run in more than 16 bit simultaneous colors.
If the DS didn't exist, then 2D games would have to be in HD (i.e. on the x360, pc, and ps3) or at least on the psp.
It's ruining the tech quality of every 2D castlevania since it's taking 2D games from the consoles, pc, and psp.
But yes, I do like the VC for every system, but those games were released in the past, so the graphics are fine and I have to give nintendo a lot of credit in that area for not screwing them up (i.e. carefully emulating them.)
I hope no one here thinks I'm retarded for thinking 2D games would be a lot better (at least in tech quality) if they were on the current gen consoles.
I'd go as far to say that nintendo should've kept the gamecube alive alongside the wii so the 2D game quality would be better than it is. Think about how much better a 2D metroid would be on the GC in 480p compared to the 98 pound weakling (i.e. the DS.)
