If i run the JPN version. Do i pick JPN region when submitting a run?

How do you see and tell total In Game Time?

What difficulty must be run on or is it any difficulty

Will the Capcom hero's be added for both NG and NG+?

Does this mean I can use the weapons or do I have to play the other Story dlc?

Is using any of the force multipliers okay or am I not about to use it?

I wanna do this solo and co-op. But I wanna know when I start my time at? I stream on mixer from Xbox one so how do I do my time from the in game time.
