@Zarnal
now I understand it was a question
do not use them they are not needed with the 4.1FE
If you go ahead with the installation in the next few days and you need help, feel free to ask I'm glad to help you if you need it.
You are the first to go beyond the usual installation :-) (at least I think so)
You can also try E-UAE if you want I will be happy to help you with this.
Excuse the question what processor do you use?
Once everything is done you will have the 4.1FE working in case you can always use UAEGFX at a later time if Voodoo3 deems it limited.
The installation principles are the same
