You can find the BeRoTracker downloads here, until the new site will be up.

Note: Because Schism Tracker started a few years ago to use the CWT TrackerVersion ID 0x4000 (after a 0xf000 bitmask) for S3M and IT modules which originally BeRoTracker was using since 2004 for S3M modules (0x4100), BeRoTracker is now using a new CWT TrackerVerson ID 0x6000 for S3M "and" IT modules, which means from now on all saved S3M and IT modules will have the new CWT TrackerVersion ID.
