This is very odd.

The files that I was going to write were exactly 696 MB.
I used MKISOFS to make an .ISO and it became 696 MB.
Then I used BIN2BOOT to make an bootable .CDI, it became 796 MB and was too big to write on a 80 Min disc.
Now why is that?

whats the name of the game ???

Of course !
When you use Bin2boot, you add extra info (2nd session) for selfboot purpose !!!
And each burning program adds its own info in images so that final images are bigger than the real files that are written.
