Having only just got my hands on the PSP and pure I'm so far only racing in vector , the alpha beta and ascension tournaments i've completed, and via single race also unlocked the Classic league...but it only allows me to race the Karbonis track, the graphics of which are not as high res as all the others. I've downloaded Gamma pack, and all this is available to me.....so how do I get the rest of the tracks unlocked in Classic ???
