R4 trouble!

why doesn't sega superstars tennis work on R4? it says game loading and then it just says "cannot read save file, please reinsert the game cart" i do this but the same thing happens everytime. please help me! :-\

do you have the latest firmware?

yes, it just won't work :-[

You probably have to wait for new firmware, sorry. There could be a patch or something on GBATemp.net if you look hard enough.

thanks anyway
