Hi! I tried to update JA1 to version 1.15.

I copied some files into the folder.

I need help regarding this:
5. Update your DOSBox configuration files and/or .bat files used to
run the game to the JAm115.EXE executable.

6. Don't use Auto or Dynamic core option in your DOSBox
configuration files, use Normal or Simple instead:
[cpu]
core=normal

Can someone please tell me what I need to do?

Kind regards from Norway.
