I have Doom, Rise of the Triad(rott), and Duke Nukem 3D.  I go to run Doom for the first time, and it works fine.  Then I install and run Rise of the Triad and it works fine.  When i go to run Doom after this, it won't play and says "Game mode indeterminate".  After this I try to play rott but it won't play and says "W_InitFiles: no files found".  If I install doom again, i can run it just fine till I try to run rott.  Duke Nukem will run no matter what, but if i install doom, run duke, and then try to run doom it won't work etc.

I don't understand this.  I WANT to just have to install a game once and run it fine always.  Any help would be great.http://www.softpedia.com/get/CD-DVD-Tools/Virtual-CD-DVD-Rom/Fantom-CD.shtml  or try an emulator.>>.http://sourceforge.net/projects/dosbox/.or just drag them to the hard drive..create a folder.......gamesi appreciate this but i'm running off dos 7.1 as my only os.You mean no Windows at all?? If you want a DOS machine, I'd try installing Windows 3.1 which is super dos compatable (ASSUMING your hardware is). In the good old days, gamers flipped between dos and Windows with the blink of an eye.if there is no way around this problem, then my very last resort would be to install win 3.1.  But where could I get that?this will run on dos7.1>http://www.vmware.com/download/sorry but unless this problem is unsolvable, I'm not going to spend money on these problems

Is this problem unsolvable?OK...  i still had the problem when I installed win 98, but only for rott this time.

I tried dosbox on my xp pc but can't stand it for itself not to mention the fact it runs like a snail even if I use the settings to increase speed.

So i uninstalled the 98 on my other pc and am back to dos 7.1.  The problem still exists.  There must be some way to fix this.

I would be willing to use windows 3.1 but I don't know where I can find it for free, and I'm not willing to spend money on a problem that can be solved otherwise, and I know that if this couldn't be solved then gaming in dos would have died a long time before windows came along.

please help me out here.  I've gotten a lot of help from this site in the past and have found if you guys don't know how, nobody that I know of does.What problems did you get in Windows 98? Did the games run at all? I have gotten Duke Nukem 3D working in 98.

For DOS box, what settings did you CHANGE? You can use frameskip to lesson demand on your computer and you can get it into full-screen mode you know. What is your computer's specs?

If the games don't even work in pure DOS, then maybe your computer's hardware is not DOS compatable.

What actually happens when you try to run the games. Do they just not work? Do you get errors?

For Windows 3.1, you might find it for free on the Internet but even though it's age old it's still illegal to download it for free. You should be able to find it on EBAY... but that will cost money.I've figured it out.  Kinda stupid really.

when I exited out of either rott or doom, the ChDir would chang back to c:\  But when I exited out of duke3d, it would be at c:\duke  so i just typed in cd c:\doom_se and then c:\doom_se\doom and it worked fine.  I just had to have the chdir set to the program's immediate directory.Do you know how to navitage your way around DOS properly? eg difference between cd xxx and cd\xxx? If not I could write a short tutorial.
