*DoubleBall       1	
(2 balls)
*Gibball          2	
(ball kills players if they don't hold rmb, which can only be held 
for a short moment)
*Keeper-Stays     4	
(keeper can't leave his box; there is a trick to get out, but it 
cannot really be done in a match)
*1 Hit 2 Kill     8	
(can kill all field players with one hit)
*Multi Jumps     16	
(unlimited jumps...floating)
*Carrier No Move 32	
(ballcarrier can't move or jump)
*Elasticity      64	
(ball bounces a lot)
*Banana*4       128	
(banana intensity increased by 4)

You can still use this stuff anytime with the console 
command (eg) map db-cube?settings=X
x stands for a number, which you get out of 
the sum of the options you want to use.
So if you want to use DoubleBall and 
Multi Jumps it would be 1 + 16 = 17
so you put map db-cube?settings=17
(255 enables all)

What I got out of playing this is that some of the things 
are actually funny for the actual game (just not that 
exagerated). Multiball will be done anyway, but multijumps 
was tasty. Maybe 4 isn't enough and 6 could spice things up 
(only boosting would become way too good again).
Also the extreme banana is kinda cool. Just not x4.... 
But IMO x1.5 or x1.8 could be really cool 
(only for side banana...up and down stays). We'll see.
The other things are mainly rubbish and can be forgotten :P
