How I got triple screen DEmul F355 challenge in 2020
Firstly have DEmul all setup and be fairly familiar with how it all works
I am using the April 2018 version of DEmul, not too hard to find with google,
Find the F355dlx.zip file in the lastest MAME Romset in archive.org
Open this and the Naomi bios zip with 7zip and copy the F355dlx zip file contents into the Naomi bios zip file
Try a couple of different ROMs if they don’t work (I’m not going to tell you where to find roms, use google)
When you launch the file you may get some error boxes, close and ignore them till your left with 4x windows
CLICK A WINDOW AND PRESS ALT + ENTER to toggle window size
Arrange your windows, the 4th window needs to be on top for the controls to work.
I hope this helps someone else trying to do this!
There’s more info in a pinned comment below!
Enjoy 😊
