In my opinion, having played the DC and arcade versions since they each respectively came out I can definitely tell the HD versions on the new consoles do not feel as quick and solid.

...Do you mean Marvel Vs. Capcom 2?  Cause I'm pretty certian that SSFIIHDR was never on DC or Arcades.

That said, didn't the Dreamcast and NAOMI use the very USB like 'Maple Bus'?  The maple bus as I understand is a serial bus with a lot in common with USB.

HD Remix is merely a tweaking of some of the gameplay features of the game.   It is 99% identical to Super Turbo.  The responsiveness of the controls should be identical under ideal circumstances.  And of course there is HD Super Turbo mode as well.  

One of my friends was looking at the NAOMI specs a while back as part of an emulation project and relayed to me that it was indeed some manner of serial input over a usb cable.

So my question to RandyT, Mon Mothma, Andy, etc.  Is there any real added benefit to using Ps/2, Serial, or parallel port connections?

It would be nice to be able to prove by testing rather than theorising, but this is not easy to do in terms of overall response. What is easy to test though is lag between simultaneously-pressed keys.
The Passmark keyboard test (www.passmark.com) displays this figure. On an I-PAC connected via PS/2 it is a consistent 1ms. When connected via USB it is a consistent zero.

I have great difficulty believing this.  Other sources put SSF2HDR as being 'heavily modified' and this makes sense.  Going from CPS-2 and Dreamcast (Which probably just emulated the CPS-2 hardware rather than being a port) to PS3 and 360, adding 720p visuals, adding full music as opposed to something sythnsized in the chip, and then getting all of that running as a NATIVE piece of software on multicore hardware.  I just think it's highly unlikely to say it's 99% the same in terms of the 'guts' of the problem and how it works.  It would be more reasonable to assume the built an original game while copying the rule set from the old game.  It's certianly not a 'port' by any reasonable use of the word so comparing them is like apples and orange.

Something like MvC2 which is PORTED from the NAOMI code to it's other platforms, including PS3 and 360 is a much more reasonable comparison.  But then look at the PS2 and Xbox1 ports of MvC2 which were largely considdered to be plagued with minor issues or 'broken' as the fighting game fanatics call it.

I don't know a metric ton of APIs or port specifications, but when something new comes out, its still supports the old stuff during the change over. I skimmed over some of the docs you and others have posted, and I get it better then you do.

Little human, do you even know why do you hate me? Never mind, I forgive you, but there is no need to be emotionally unstable over technical discussion and blame me for your inability to understand, relax. You have some opinion, that's great, all you have to do now is find some source and quote it here to back it up.

--- End quote ---

Thats the easiest way to prove that keyboard input (post Windows 98) does not go via the motherboard keyboard controller, as turning this off disables this path.

--- End quote ---

False. Turning BIOS legacy support off will only disable hardware level PS/2 emulation, and so Windows will use its own emulation driver, that will be doing the SAME THING - interfacing with keyboard controller and port 0x60.


Is this Microsoft page outdated and simply wrong:

XP does NOT use the port 60 route. Can you show us anything on the web that says so? Or perhaps that's some mysterious unspoken truth everyone is supposed to believe without questioning?
