Hi Mr Wych
It's going to be both - because of the really small nature of the roms and what have you, you can browse it from the DVD and run the games, etc. with no problems. Same really with the Zzap 64s as they're around 30MB each.
However as I know most people would like it to run from the HD there is going to be a copy routine (and probably an Autorun on DVD / CD) to copy everything to HD (or just the C64 Roms minus the magazines) - I'll probably be enlisting the help of Mr DamienD for this bit.
Then theres a few reg tweaks and we're good to go.
I'm glad to say that now the Zzap 64 is complete - having just had a look at the filesizes up to yet it has now gone over the single DVD mark - yes I do have a dual layer burner but the cost of dual layer disks are stupid still.
Anyway attached is a picture of the filesizes - lol
