Here's a snippet of the interview Gamasutra did with Capcom producer Hironobu Takeshita regarding their upcoming Mega Man 9 WiiWare title.
Gamasutra: You talked about how people were trying to graphically exceed the capabilities of the Famicom, but what about the temptation to exceed some other capabilities, such as flicker, slowdown, sprite limits, and stuff like that? Was it really hard to get people to stay within the confines of what they could have done, if this had come out after Mega Man 6 in 1993?
HT: Yeah, there were some things, like you couldn't have more than three enemies on the screen at once, so we had to make sure that that's how it stayed in our game. In the part with the dragon with the flame, [there should be] flickering, and whatnot.
In the options of this game, you can adjust that, unlike the old games. We purposely put some of those old-school bugs into this game, so it does recreate that feel.
It's clear that this title is really shaping up to be quite the trip down memory lane for 8-bit era fans. As usual, we'll have any more new developments on Mega Man 9 as they become available.
