Go Macca, Go! Looking good. I'm definitely going to finish that C64 bloodwych!
Converting all those Zzap isn't a small task - that's dedication for you! Is it going to be HD installable only if it spans more than 1 disk? Have you got a dual layer burner? That would soon eat into your pocket sending DL disks out!!!
To be honest, I think most people would install this to the HD anyway rather than play from disk.
