Cloanto is also mainly a publishing company. But they have for decades sponsored Amiga development in various ways, for example they made "Workbench 3.X" happen, a re-make of everything essential on "OS 3.9", they have published updated OS distributions of all OS branches with date fix, support for big harddrives, etc, including the ROM's, and they have sponsored WinUAE development in various ways during the years, including Toni Wilens work on PowerUP emulation to be able to run OS4 in WinUAE/Amiga Forever. The most important work IMHO however, is the fact that they have managed to secure IP from various sources in various ways, bringing together everything under one single umbrella again, thus securing a possibility of Amiga (both as retro and NG development) having any hope of a future. Things can only become better now as a result, thanks to Cloanto.
This!
If there is one currently active Amiga company that can handle the IP the way it deserves, that's Cloanto IMHO.
