Product Overview

JiffyDOS is a Disk Operating System (DOS) enhancement which gives your C-64 or C-128 the disk access speed it has always needed. A chip-for-chip replacement for the Kernal ROM in your computer and the DOS ROM in your disk drive(s), JiffyDOS achieves levels of performance and compatibility unmatched by other disk speed-enhancement products. Outstanding speed, solid compatibility with virtually all hardware and software, and a new set of desperately-needed commands and features, gives your system a new lease on life and the power to compete with today's newer, more-expensive machines.

JiffyDOS should not be confused with Cartridges, Turbo ROMs, Burst ROMs or "Parallel" systems. Ultra-high-speed multi-line serial technology enables JiffyDOS to outperform these products without any of their inherent disadvantages. JiffyDOS leaves all ports on your computer open, works with virtually all software, speeds up PRG, SEQ, REL and USR files, and does not require any extra cabling. Owning JiffyDOS also gives you access to some of the best product support available.

    Perfect for MiSTer setup to speed up loading software

    Posted by Chris on 11th Feb 2021

    I don't have real hardware C64 for a while, but MiSTer based setup with JiffyDos works like a breeze.

    Essential

    Posted by Alan Reed on 12th Aug 2020

    For more than twenty years, the first order of business with any new Commodore computer has been JiffyDOS. It's that important to me.

    Excellent offering

    I'm using the overlay image with VICE. As a user of JiffyDos ROMs, I prefer also being able to use them with the VICE emulator. Many thanks to Jim Brain for making the images and all the great Commodore products available to us!

    top floppy disk accelererator for commodore c64

    Posted by Cassyan on 12th Nov 2017

    Excellent product for any Commodore C64. Definitely one of the best with many variations (patches) out there. Instant delivery after buying it with a download link. I used it to burn an Eprom for my C64 Reloaded board. This is the software needed for replacing original kernal rom (IC / chip) with an Eprom (IC /chip) for c64 to gain speed for floppy disks. Thank you Retro Innovations for making it available.

    works on easyflash 3

    Posted by Jimmy on 15th Oct 2017

    This works great loaded onto easyflash 3, so no need to open up the good old C64. It really speed things up. And it seems to be compatible with all I tested.

    I love JiffyDOS!

    Posted by Mike on 17th Apr 2017

    It might be the best fastloader out there for C64. I got it for my C64 and 1541. It's so much faster, and the DOS wedge is easy to use.

    Excellent product

    Very easy download and effective. This should work to use JiffyDOS with VICE and SCPU option.

    A money saving solution

    Posted by Ray Carlsen on 23rd Feb 2016

    I like the idea of buying just the code each time because I can program an EPROM myself. That saves time, shipping and the end user some money.
