i'm brand new at this stuff. HELP?
 

how do i burn games? do i need anything special to play them on my dreamcast?

When you have found some games, you can use discjuggler (most common), nero or cdrwin to burn them, you dont need any special thing on your dc, you the bootcd with games that arent selfbooting. For further help i recommend some of the help posts you will find in this forums...good luck!
