Downloads

The main difference to existing firmwares is that we will no longer be publishing patchlists, because that left room for errors in the past. Every new version will get new files (XDF and ADX) that will come bundled with it.

We will only link the newest version in this main article. For legacy versions check the download archive: MS43X Firmware Archive
