Honestly that's the one thing I've been worried about with this game, maybe some kind of WiFi key like Daigasso Band Bros DX used, that or a Hunters License type thing like SEGA done with the old Dreamcast version.

I was planing to be online with this a lot over the next couple of months, so if PS0 one ends up being a pain in the arse to run off flashcards  i think i'll just end up importing it.
