1. Yeah, I've thought of it. It would take some work, but it's the kind of stuff I'm interested in. :)
There's a nice little guide on GameFAQs (which was one thing that made me want the Dreamcast
version more), but it's very incomplete in some areas (it leaves out most of the glitches).
2. Yeah, basically what Paragon said. On GC, you have to wait until Chaos lands before letting go of B
(or at least it seems that way). I think F-Man attacked earlier by playing on Dreamcast.
About E-101 mkII... ugh. (Look at my position on the board.) I haven't really spent much time at all.
I'm pretty sure all his attacks always happen, but it seems like you can speed up the battle a bit
by avoiding threatening him (going toward him, for example, makes him fly around and waste time).
His patterns probably are completely controllable. I know Chaos 4 was like that.
Check the guide. I'm thinking there could be a few inaccuracies (I'd have to check again
to see exactly what it says, but I remember that I get the same results, even though I don't
play the same way), but overall, it explains the patterns well.
