This PC port of Mega Man X8 doesn't get enough respect. Compared to the trainwreck that was the Korean-only PC port of Rockman X7 by Multi Enterprise, this PC port of the original Mega Man X8 was fairly solid. A few visual effects looks like it got downgraded a bit compared to the PlayStation 2 version, but you can play this beyond the typical 640x480 resolution that was common some in Capcom's older PC ports around the mid-2000's (up to 1600x1200 though), it has 3D positional audio to make up for the lack of Dolby Pro Logic II surround sound, you can actually remap most of the keybinds, and unlike the X7 PC port, you can also use a controller as well with rumble support (granted it's DirectInput-based, before native XInput became more commonplace with PC games). The other cool thing about this PC port is that it has dual-audio tracks (provided you're using the 2-Disc releases of the game because there are 1-Disc releases of Mega Man X8 PC in some countries with language options being limited to whatever region it was from) and it also had the Japanese intro music,
WILD FANG by Janne Da Arc (the video itself however is slightly edited to remove the "Rockman X8" branding if the game was install with any other language option besides Asian/Korean/Chinese, but it's a minor nitpick).
The downsides are the PC has no graphics quality settings (so no anti-aliasing, anisotropic filtering, etc.), and even at 1600x1200, the internal resolution of the game looks rather crunchy. Some keybinds are hardcoded (sadly the Arrow Keys, Space bar, Enter, and Esc are reserved for player movement, answering the Navigators, Confirm, and Menu/Cancel respectively). Despite having better frame-rates than the PlayStation 2 version (assuming it was above recommended requirements but that's not really an issue on current computer hardware), it does have some loading hitches as the game tries to load certain things in the background in some places that I wish could be eliminated outright. It's also sadly one of those older PC games that don't use the D-Pad if the controller has an analog stick too like many modern controllers, so the game uses the Left Stick to move instead of the D-Pad, and despite favoring DirectInput, not all DirectInput-based controllers will be fully compatible (if at all). It should be possible to fix some of these issues like the low internal resolution with dgVoodoo 2 and set up Xidi + Hookshot so it cooperates better with XInput controllers, though I wish there was a more convenient/drop and forget kind of set up to make this port work better on modern systems.

This includes the japanese voices, right?
Yes but only voices for some reason.
That's sadly another weird thing about the PC port of Mega Man X8, not all supported languages are installed into the game itself. So for example if you told the game's installer program to install the game in English (USA) during the installation process, the in-game Select Language setting in the Main Menu will only offer English (USA) or English (UK) for text and English or Japanese for voice-overs. So if you speak for example German, you'd have to install the game with the German option. Don't know if it was a memory limitation at the time, but still sucks regardless.
