Whoa, Kamui. Most laughably bad post of yours I've yet seen.
Rondo on the PSP is awful due to the really blurry visuals. Really, it ain't pretty. The audio's also way out of sync with the video during cutscenes. It's a terribly flawed port; there's definitely room for improvement.
Saying Rondo is shit compared to Super Castlevania IV is ridiculous. Both are incredible games.
Besides, Rondo is already on the Wii Virtual Console; there's no reason Nintendo shouldn't port over the Wii's library to the 3DS and allow those who've already bought a game on one VC system to play it on the other.
Anyway, Nintendo really need to fix their sheeit when it comes to Game Boy games on the 3DS. Downloaded Kirby's Dream Land and the visuals are really fuzzy. Downloaded the 10 Ambassador Program NES games, played Super Mario Bros., and that looks awesome. Wonder how/why they goofed up the GB games so bad.
