Yes, for DOS I use DOSBox, my question was more related to old Windows games (Windows 9x)
QEMU works quite well, I have it with Windows 95, I also have a VirtualBox with Windows XP (the tests I did went very well), but you say that VMware is better so I will try it.
Will VirtualBox/VMware work well if I install Windows 95/98 on them?
To install Windows 95 in DOSBox, which of all the existing versions of the emulator is the best?
