PS3HEN is not officially supported but a modified version can be found here
multiMAN now recognises the offsets for FW 4.83/4.84/4.85 and displays the firmware correct version
Thanks to this update, unofficial versions of multiMAN with support for CFW 4.83-4.85 can finally be put to rest as the modifications they did were possibly not ideal. However, no word has been shared on how compatible with PS3HEN this version of multiMAN so users of that should still stick with ManaGunZ.
