Why is the Famicom's video output shifted one tile to the right?

[UglyJoe]

Do the creators of iNES know Nintendo is using their emu?

iNES is a header format created by (illegal) cart dumper manufacturers.  It's not an emulator.

Well, I guess, that's what I meant...
Do they know that Nintendo is using iNES?

For all intents and purposes, there is no "they".

edit: Okay, I guess "they" is Marat Fayzullin (http://fms.komkon.org/).  If he cares to know about it, I'm sure he does by now.  Also, apparently iNES is an emulator as well.

As a side note, speaking of NES emulation accuracy on the Wii, L___E___T posted that the "video shifted one tile to the right" behavior doesn't happen on the Wii, that means it's not 100% accurate and true to the original hardware anymore, and also I remembered that the Wii VC version of SMB3 doesn't have the status bar glitch present on the original version: either the emulation is compensating for it (making it not-100% accurate again) or Nintendo simply fixed the glitch in the original game (having the source code).

Yeah I wanted to remark that, but I didn't wanna get pedantic and we all knew what nintendodork was referring about .

I was gonna say, I was almost positive iNES was an emulator, but if iNES was my creation, and I didn't know Nintendo was using it, I would demand money

[UglyJoe]

Well, they're only using the header format he came up with.  Going after Nintendo for using a 16-byte header of your own creation would be a very difficult feat.

Reading the history of the iNES emulator's development here was interesting:

http://fms.komkon.org/iNES/

It was only the second NES emulator ever after Pasofami, it was the first to use the .NES file format (and therefore iNES headers, right?), and was released in 1996 ... for $20.  And if you want it today, you still have to pay for it.

OK, what is this "video shifted one tile to the right" issue/characteristic you're talking about?  You never explained it in this thread...

And regarding Nintendo's Virtual Console emulators, I highly doubt they went back and modified the source code for SMB3.  Making an inaccurate emulator is probably the easier option (and we already know they did that, don't we?).
