Well, it's that time of year again and the Christmas demos are up on the c64preservation site. :)
I've released a new version of nibtools today- not a huge release, but a requested feature for the tinkerers. You can now change the extra capacity margin settings with the -m switch during writing.
In older versions, it was automatically a more aggressive setting of 5, but newer versions were 10. The size of the track is measured several times internally and the largest difference is added to this number.
Just -m by itself will have no safety zone at all other than the maximum measured capacity difference, which will surely result in some tracks overwriting the start of their own track data. So, use this only for tinkering with certain protection tracks. Putting a number after '-m' adds bytes to the safety zone.
Not using '-m' at all still produces the old behavior of measured+5 bytes.
Background: We are writing track data that is essentially a circle and "destroys it's start" if you write too much data, so we have to be careful not to write too far. These drive mechs are old, and most are belt driven, so there is a needed safe zone of 5-10 bytes, typically. Non-belt driven drives (1571, and some 1541-II) are more exact and may work fine with no safe zone.
--* New nibtools release and Happy Holidays!
