Yes, very old DOS-based games from before 2000 can be emulated perfectly. If you have a modern computer, even the later SVGA 3D games running in protected mode are no problem (using 100–200k cycles/ms in DOSBox).
In fact, today’s graphic possibilities and available monitor resolutions make it possible to accurately and aesthetically simulate an analog CRT monitor with its scanlines and aspect correction (DOSBox Staging). But of course you can just use big sharp pixels.
