Many of thouse more modern emulation tools / software is detected as some kind of virus cuz they in fact are some kind of hacking / cracking tools / software.
I use the 1280x768 .exe and change the Resolution in initialD.ini to 1280x1024. This way i loose some of the Screen on bouth sides becouse the image will be stretched but i can life with it.
P.S.: I use TeknoParrot Loader only.
Well i'm waiting for a 1280 x 1024 .exe for Initial D - 6 AA too.
But guess it may will not be possible or look strange becouse Sega RingEdge use 16:10 ( 1920×1200 ) native.
