Well people I posted this topic to ask for some help, I have Windows ME installed and I don't know if it is my computer or windows fault but every time that I put an old DOS game in my computer like Carmen SanDiego or Prince of Persia it crashes and I have to reset the computer. Don't ask me why but games like Doom or Wolfenstein 3D work perfectly. Apart from that I tried to use DOSBox and I do everything that tells me to do and I can't make the game to work, I just don't understand it.
Sorry for my long posts but thats how I am . Help is welcome.
