Weird... read my mind on that one, SGraff... Looks like the perfect opportunity for you to bring back the Super Gameboy War project that didn't get anywhere before. (Not tryin' to insult it or anything, I was really hopin' it'd get further than just the palette.)
Also, while I'm posting here, got some comments and a question pertaining to the graphics.
I just recently noticed that the Bullet Bills now have the fourth frame! Awesome! Although, I forgot how I was gonna revamp the NSMW one to use 4 frames...
Not wanting to complain, but I was totally confused about the layout of the supersmash graphic. I finally figured it out, although it's still pretty strangely organized. Hopefully other people that decide to change it don't have as much trouble.
As for the Pipe Minigame powerups, I honestly don't understand how a flipping Zap-Tap Badge (looks like one, at least) came out to a slowdown effect for the pipe... Personally, I think a vertically flipped speedup powerup changed red would suit it quite well, but that's just me.
And I've got a question about the kills in a row graphic. What's the second ! block for?
