MultiWii

hi,
my Jakub board is in use as paperweight.
I'd like to change that - has someone of the community updated the firmware using mw 2.1?
not much work but I have not much time and i am off for the next few days.
thanks for your help in advance!

Firmware 2.1 from FC Kuki is here http://telnet.r-ce.pl/quadro/multiwii/MultiWiiConf_2_1_063_full.zip

thanks Jantar,
saves me quite some time.
will test if my filtering is applicable to the 8bit world.

EDIT:
i added the simple filter (not the one with less lag).
the looptime is 3300 3400us and 3 kb of flash is used.
with no baro and mag code enabled as the the board is missing those chips.
