You can use old computers on Lcd, don't need a CRT for that. I use them on my Toshiba all the time. Per telling the difference, I can right away when I hear the games audio. This is a problem anyone running VM, Dosbox, or even GOG re-releases face when trying to play the classics on Xp-Win 7 machines, etc, who grew up with and know by heart how the original stuff sounded on the old soundcards.
This is even a problem for many people who prefer SB16/Pro for some games and something like the Gravis Ultrasound for other specific titles, so they run multiple sound cards in their classic machine. I guess this is the difference though between someone who knows and expects higher quality (a classic pc gaming enthusiast with hundreds of titles in their library), versus someone who doesn't care and is just happy being able to, on a whim, run whatever specific game they just downloaded on a whim, at totally minimal effort (f*ck all if it actually looks or sounds right, let alone plays at the right speed).
This just sounds lazy and stupid to me. Thanks, but no thanks. You're basically making the same argument the emulator die hards make. All I can do is say meh, to each their own. But no one leaning on the lazy side can damn well sit there and try to say it looks and sounds perfect, because it damn well doesn't and never will. And to me, if you are going to be this lazy, if there are any available, you might as well just buy or steal the GOG releases at that point.
And to note, it is all downhill from there.
Also, where did XP come into the discussion?
