Create G64 disk image using real hw: possible?
There is a way to create a G64 image using only real hardware? |

It 's just a matter of laziness. I do not want to install all drivers and hardware using a pc...
I know there is a way to create .d64 (from 1541 to sd2iec or to 1581 for eg.).
Then i thought that someone had created something similar for G64 and "protected" software... |

Is there anything out there which can do the reverse? Any idea how powerful the six-pack writer is?
You can squeeze quite a few extra kilobytes onto a floppy by abandoning the standard format, but it's difficult to distribute the resulting demo/game without tools for the users to dump the results back out using standard equipment. |

it should fail at the obvious stuff: index alignment, non standard bitrates (tracks recorded with slowed down drive) and probably also with different densities within a single track.
besides that it was good enough for a generation of crackers to swap their originals :) |

Quoting Groepazit should fail at the obvious stuff: index alignment, non standard bitrates (tracks recorded with slowed down drive) and probably also with different densities within a single track. Cool :)
I'll give it another shot with the non-standard bit-rates stripped out and the inter-sector gaps lengthened. |

Well, in theory all we need is the best nibble copier around and instead of writing to a disk it has to write on a file on a different device (where possibly there is an sd2iec or utilamet2+ or something like that).
Basically is what nibtools does but on c64.
The same drivecode of nibtools could be used directly.
Or something better than that if there is. |

Maybe some of the code from here could be used/adapted, for using the ultimate as storage device.

nibtools is basically burstnibbler (the drive code anyway).
MarcusC64 (iirc) made a version that writes the raw data to REU memory and can dump that on 1541U or similar setups - and then you can convert the resulting data into a g64. Its still a bit hit and miss though, and requires manual work with non trivial protections, because certain things cant be handled automatically (different speeds on a single track, track alignment, weak bits) |

*bump* Bits and Nibbles : The Ultimate Copy
Thought all the drive freaks would dive into that and see what it does :) |

I was thinking about the best nibble copier around which *seems* to be the one in maverick.
Or is burstnibbler/nibtools code better? |

Burstnibbler uses parallel connection to begin with, which is pretty much a requirement for a proper nibbler (unless you install extra memory in the drive).
For Zoomfloppy (or similar purposes) it doesnt really matter anyway, as the drivecode can be relatively dumb, and all the complex stuff can be done on the recieving end. All you need to do is read a full track raw and send it over. |
