I rainbow starred all 23 or whatever Mario levels. I didn't really notice any input delay. Played on the TV as well as only the gamepad. After seeing so many people complain, I might have to dust off the nes just to see if I notice a difference.
Edit: Just played on the SMB/duck hunt cart. Honestly, felt pretty identical to me.
People aren't imagining the lag. It's there.... I could feel it immediately while playing on my lag less tv. The same tv I play other mario games on via Wii VC, the same tv that I play my 360 fighting games online with.... It's not a gamepad latency issue. It's a NES REMIX issue.
Edit : and after a quick search.... Here's a review where the guy singles out the SMB portion of NES REMIX for lag.
I'm not saying the people who don't notice input lag are wrong, however for myself I grew up on Mario and I can tell instantly the timing is off. Especially in the level where it auto-runs. As mentioned before, it isn't my TV as I have played VC/WII Emu versions of SMB which had no noticeable input lag.

^I think you have a point there. The stages where I notice A LOT more input lag are definitely during the auto-run stages. In fact, the first time it jumped at me was the auto-run Remix stage with Chip-Chip on the air bridge (2-3 from memory). The lag was A LOT more noticeable there then on normal Mario stages (for exemple Bonus Stage 25. With 44 parts to do, if the lag was as bad as the 2-3 autorun, it would have been atrocious to do a 3 Rainbow there).
Please take note that, again, it doesnt block me from doing Rainbow Star (I now have all 612), BUT I can't close my eyes on this too. Its noticeable, BUT I will give to people that yes, it's even more noticeable during auto-run stages.

Strange, I almost wanna say that maybe its possible some of you that downloaded day one have the issues. I've beat super mario bros at 5 years old so I'm qualified to speak on timing lol, I'm having no timing issues on Nes remix it is spot on for me. now the wii u super mario bros vc timing is horrible It made me so mad, think about this though some of us are having timing issues on wiiu vc and some on nes remix Im thinking it could be a bad gamefile? Try redownloading maybe?
