I built a cross-platform tool for making CDJ-compatible USB sticks

I got tired of needing Windows just to prep USBs for CDJs, so I built my own tool. It reads, writes, and repairs DJ USB sticks (short of actual hardware failure), and the exports are compatible across rekordbox, CDJ-2000NXS2/older, and CDJ-3000 — not just "works on my machine."

Works on Linux, macOS, and Windows. Local-first, no cloud dependency.
