Please, please, pleeeeeease don't say this word.
There is no such thing as "soccer"!
I know, Americans call it soccer - but that hurts. :mad:
The game is called "FOOTBALL" because it's played using the feet. What's your excuse to give this name to a game where some guys carry an egg? :devil:

yup. btw, i don't look at it much. but, notice the last flag before unregistered, was a result from previous call that always zeroing the return value. i don't get this. is this somekind of buffer overflow exploit?

Competition is still technically not over, but...
[SPOILER]
Do you mean the jump at 4018EC? That's just some exception handling cruft. The actual decisions are earlier in the function.
