Today I want to share an online site I built that is an easy browsable collection of LibreDrive firmware.
Here it is: https://firm.ld.tpglit.ch
Important Note: This firmware collection is not officially associated with MakeMKV or its developers. The collection is based on this topic: viewtopic.php?f=16&t=19634 and will be updated upon request or when I notice an update.
