Extended ADF

[Seiya]

What is the different between an extended ADF and normal ADF?

[stx2199]

the normal adf are images of common floppies without copy protection
the extended adf is for games with copy protection

[a/b]

Extended is MFM encoded raw data (0's and 1's that are actually written on the disk), about twice the size of a normal ADF. Allows for custom layouts and all kinds of shenanigans.
Normal is regular (MFM decoded, standard Amiga DOS layout) data. For example, if you load an entire floppy disk into memory in some kind of a monitor or asm-one/pro/... and look at hexdump, that's what is in the ADF (and you could save that chunk of memory as a normal ADF).

ok, i thought was special version with some features that in normal adf missing.

No, it does not.

a/b already gave the correct answer.

Easier was to say it: normal ADF = actual data after MFM decoding, Extended ADF = data still MFM encoded (so longtracks and some copy protections are possible)

it could have more space if you used diskspare.device (which would require extended adf). It basically just allows custom disk formats (but isn't capable of storing all possible custom formats)
