Just informing everyone I have made an update to the Atari VCS EFI.
This EFI will now run High Sierra, Mojave, Catalina and Big Sur (up to 11.3).
By default the file is setup for running in Big Sur, but should work in the
other OSes. Please add in your serials and rom as necessary for EFI.
I've made some improvements such as addition of USBMap.kext as well
as a modded SATA-unsupported.kext to allow the internal drive to finally be
usable/seen. I have also made a custom SSDT for the Vega 3 internal gpu,
which now allows it to run DRM such as Youtube and MP3 file playback
but it is not running official 3D hardware accelerated option as yet.
Sound may be a little choppy on Catalina. I had tried to reconfigure Rehabman's
FakePCIID_Intel_HDMI_Audio.kext for the AMD chip but it has proven
somewhat challenging despite the sound chips being recognised in System
Profiler PCI devices. 4K and HD res switching is now also available.
WiFi is also now fully functional in Big Sur, and Ethernet on LAN port is
available across all the OSes. USB 3.1 is now also available across all ports.
If you are using Mojave or earlier, please select and use the USBMapLegacy.kext
instead.
