Hello, guys. New to gbatemp (though I've technically lurked for years). I've read some of the faqs and stuff and am ready to purchase a flashcard. Specifically the supercard dstwo+ coming out this month (apparently). Anyway, my question is this: Assuming i wish to play roms online will I have to use headers or is that something exclusive to gateway? I can't seem to find enough information on cards that aren't GW. Any advice would be appreciated, thanks. (Also my sysfw ver is 9.4 (U) )
