Okay so I downloaded DOSBox 0.72 on my computer with Vista.
I downloaded two (2) games for it:
1) Super Solvers Treeasure Mountain!
2) Win, Lose, or Draw

The problem with Treasure Mountain is that everything works up until I try to install/run the game.
It keeps asking me to "insert disk 1 of 2". I don't have the disks, so I follow the directions that say to just "Press any key to continue". After that it tells me just to type "RUNME" in order to play, however when I do type it, it states that "RUNME" is an illegal command.

The Problem with Win, Lose, Or Draw is that I can only hear sound.
The wondow pops up and I can hear music, but there is no picture.
I don't think the music sounds any slower than normal, it's just that I can't see anything.
Even when I press "ENTER" I can hear sounds, but still no picture.
Someone told me that I needed to increase my CPU usage, but I'm new to all of this and I don't know how to do that.

I hope I have been detailed enough. Like I said I'm pretty novice when it comes to this, and I have a LOT of questions.
What should I do?
Any help is appreciated.
