Alternately, if anyone wants to mail me the memcard and an extra prepaid return envelope, I will happily mod any ps2 memory cards promptly. PM for mailing address.
The process is incredibly simple though, so any tourney you go to should have someone with the capability to mod a card for you. Just to be sure though, posting in the appropriate regional thread, a thread for an upcoming tourney, or asking on IRC is probably the best way to get in contact with people.
