trouble finding progs

[Anker]

hi
i have one of the newer dreamcasts that doesn't play cdrs...i tried using the megagames.com dc bootdisk work around for the non-cdr ones...but a problem arrived when i needed to get the programs mkisofs or cdrecord-tools....and i can't find a working program of mkisofs or cdrecord-tools...well i got both programs but they don't have executables or a file named mkisofs to work with in dos/command...it might be that i don't know how to use the program but i don't really know what i'm supposed to do now and am really confused....can anyone help? a working link? tips? comments? thanks
