I have confirmed the operation of this game on Japanese Windows 7 SP1 x86 (VirtualBox 6.1).
Notes: Textractor works. Disk 2 must be kept mounted to hear music. I don't think this game has a windowed mode. There is map movement in-game.
Additional Note: When I first tried playing, I couldn't see any text in-game. Text became visible after changing the bottom most setting (second picture in the spoiler) to OFF.
A given mission, mechanical assault, manufactured devotion.
Red eyes, an upside-down form. Even the twisted shape was made to be that way.
No matter how cruel the slaughter, worse than a demon's,
or how gentle the kindness, greater than an angel's,
a machine has neither will nor madness—only code, and a few bugs.
So why, then, does it feel so unbearably sad?
