It took me 11 games of D2K on the machine, but I finally cracked 200K just now. 241,500, 7-1.
So I'm now pretty much right where I left off on MAME (256K, a few screens further).
Last night, while looking at a game, I realized two very important facts about the barrel screens that just made them a lot easier. To be honest, I'm a little embarrassed that I didn't see them until now.
First is that you can always kill the lower fireball if you immediately grab the bottom hammer and go right for him, which makes that approach something of a no-brainer going forward.
Second is that, past level 2, D2K Kong doesn't release any blue barrels other than the first "triple fire" barrel!
Somehow I'd just never caught that before. Duh! This changes the strategy greatly for the barrel screens, in that now I know I don't need to worry about the danger of waiting at the bottom, since there IS no danger. I can hang out until I'm comfortable with what the upper fireball is up to.
It also opens up an interesting point-pressing opportunity, in that, should the second fireball go all the way to the top, you can group and rejump until the timer is out without ever having to worry about fireballs coming up from below to get you.
Onward to 300!
