I am using Winuae to do that but WB 3.1 does not recognize this CF card.
I'm trying to install WB 3.1 for my Apollo V4 without Apollo OS and balenaEtcher
here a post which explains the required steps.
EXTERNAL LINK You need WinUAE, CF-Card, CF-Card-Reader/Write and a Windows computer.
No balenaEtcher required.
EXTERNAL LINK I personally have never tried it.
