Firmware mods for the Pioneer CDJ-900NXS. We took the player's firmware apart in an emulator (QEMU, extended for the player) and added what newer Pioneer players have: hot cues on the deck, beat jump, colour and 3-band waveforms, keys in Camelot colours and more.
Pick the mods you want in the builder. It patches the official 1.31 update in your browser and gives you a normal C900NXS.UPD to install like any update. The boot loader is never touched, so you can always go back to stock.
