Dreamcast Virtual memory Unit (VMU)

Just have a problem with the VMU I don't think it's broken but it doesn't save new games. It must be because there aren't enough free blocks.
Anyway how do you delete memory from other games so you can free space up to save new games?

hmm... if my memory serves me right, try turning the system on with no cd in it and then i THINK it brings up a bunch of options... i might be wrong tho

Yes that was it.. thanks alot =)
