In my layout, absolute mouse is working fine. 🙂
Block mouse move & msmouse are already pre-configured, and auto correction is set to the game’s resolution (640×480). Not sure if on phones with lower resolution or different aspect ratio than my old S7 (1.440 × 2.560 pixels) need a different setting, but that shouldn’t be the case.
You will always need to recalibrate the mouse ingame, as the Win95 / Diablo combo can mess it up. But I automated this in the profile, too, so it shouldn’t become an issue, either.
