    SD2IEC with FC3 would also have been interesting, this is, how i have it in everyday use here, when i utilize my SD2IEC.
    I guess, the speed will be somewhere between JiffyDOS+SD2IEC and EpyxFastload+SD2IEC. It’s interesting how much faster the SD2IEC-compatible modul-fastloaders are, compared to the speed, they have, when a 1541-floppy is in use.

    Software-fastloaders like “Transwarp” are impressive, the speed they bring. Not ideal i find, that a disk must be prepared before, that this loader then can be used, it can not only be put as a file on the disk, then loaded and then works like other software-emulators. But therefore, “Transwarp” is a faster than the others, seems like you can’t have everything *lol*.

    By the way, another interesting software-fastloader is “Mafiosino Trackloader”, which has around 20x speed and can load a 200 Block file in around 5 seconds, which is similar to the “Dolphin-DOS” speeder-kernel. And if we are already writing about speeder-kernels, then “Prof-DOS” must also be mentioned, which is even faster than “Dolphin-DOS” and is probably comparable to “Transwarp”, in terms of speed.

    I wrote my own fast loader in the mid 80s, it loads 182 blocks in about 5 sec or less depending on initial seek time.
    It can also write at the same rate but I never bothered to finish writing code to handle the checksums on the sector data. I called it Nitrox and also started working on backup program it can read an entire disk in about 22s. I posted all the details on c128.com quite a few years ago.

      Sounds interesting Craig. Can you upload an executable version of your Nitrox fastloader somewhere on the internet? I am sure, it would be interesting for alot of people.

    Can you upload your loader somewhere on the internet, Craig, so that other people can also use it? Or was it just a joke from you?
