Thanks for the reply. The way you do it looks different, I've never seen it done like that. I am doing it the same way I've been compiling since, I don't know version 0.146 when things changed again - just like the directions say:
make all -j5 OSD=winui PTR64=1
It works for command-line MAME (minus the OSD=winui), why would that make it any different.
