Tired of waiting for your 1541 to load? In this video, I’m upgrading my real Commodore 1541 disk drive with the legendary JiffyDOS replacement ROM. When paired with the JiffyDOS kernel in my C64 Ultimate, the read/write speeds are incredible—up to 15x faster than stock!

Note: This is a "silent" tutorial featuring a text-based walkthrough and no voiceover. It’s a raw, step-by-step look at the process.
