You can only choose the 'version of the release game', that was inexistent on PC version. Lack of customization: You can't choose the language you're playing and the voice you're gonna hear. A mode that I could use without problem with the PC release. Menus, submenus, textures of the life gaugue, icons, any image model at all, bosses menu: All pixelated and stretched specially if you use wide-screen mode.
Wait time to save game, PC version had almost none. I don't know about you guys, but I can say with 100% certain that Megaman X8 on this collection is the PS2 version.
