Small review on ApolloOS_R9.4:
ApolloOS_R9.4 comes on a zipped HD image of about 5.3 GB that when unpacked you get a Disk Image that includes 2 SFS (Smart File System) formatted Partitions, of which 251 MB dedicated to the Operating System (DH0) and a second 7 GB dedicated to data (DH1), see first screenshot above.
To lighten the file I decanted the Operating System and a few important applications used by the system onto a new 1GB HardFile also formatted in SFS, ready to be booted independently on WinUAE, see second screenshot.
ApolloOS to make it boot well on WinUAE some modifications are needed, in addition to a 060 CPU with at least 256 MB RAM, you need to boot it via an AROS 68k ROM, ApolloOS on the VA boots via some commands and native Apollo ROMs.
On WinUAE in addition to the not too recent AROS 68k ROM (tested even with the newest ones and it seems they are not supported yet), you also have to integrate the Icon.library into the startup with the usual command used for the Icon.library by PeterK.
The appearance of Apollo OS is pretty also the Icons many of them Dual-PNG are of good quality and of the same size, the system is not complete for example it is not possible to replace or add a new Pointer.
ApolloOS in addition to the AROS ROM, also includes some AROS library, but otherwise all system Apps are OS3 based, native AROS Apps are not supported because there is no Zune interface on the system, instead there is MUI 5.
Overall it is a good system but it needs to grow !
