Sorry for my late reply PoulpSquad, I didn't notice that you have updated your last posting here.
As I already said above, I never play any games and I have no knowledge or experience with WHDLoad. So please tell me exactly what I have to install and to try out on WinUAE to reproduce your problem with these slaves and their icons.
Concerning your question 1.) There is the Amber Ram Disk as a possible replacement which I use myself on my WinUAE system.

2.) Don't know, never tried that?
3.) Do it the same way as AmberRAM uninstalls the RAM Disk.
