DOS problem....

edited July 2017 in Chit chat
Okay, so a while back I picked up a disc in a charity shop full of old PD demos and games for PC....most of which run in DOS...

When I first started trying them out, they were working fine on my PC (which runs Vista)...but now, even if I try game that worked previously, I'm getting this message when I try to start them up!

Any ideas why this has started to happen, and any way I can get the games to run again?

  • If they're really DOS games, use DOSbox. Period.
    I was there, too
    An' you know what they said?
    Well, some of it was true!

    Yeah, I've got a few games that start automatically in DOSbox, and they all work fine...

    It's the fact that the games from the CD worked before and now they don't, and every thing I look up tells me it's because I use Vista...so how did they work fine until today?? Very confusing!
  • I'm surprised that they worked before, but...

    AFAIK, Vista introduced some changes into video drivers and NTVDM that made harder playing with DOS games so I won't expect them to work. Also, 16 bit programs (DOS, Windows 3.x and even some Windows 95 games) won't work at all on 64 bit Windows.

    Maybe some update from Microsoft or a video driver update made fail your games. Or maybe you could try to run those games as administrator, or put them on Windows 98 compatibility mode.

    The safest way to run a DOS program on Windows is using DOSbox, as I said. Keep on mind that NTVDM won't provide complete VGA emulation, and sound blaster emulation is bad (unless you use VDMSound, but it is not available for Vista).

    IMHO, the latest Windows OS that could run DOS programs easily was XP... I didn't even try to do it on Vista.

    (BTW, VDMSound included some tricks to run DOS games on their documentation... maybe some of your problems are solved there)

  • havent you got an old lappy / pc you can just use for the really old stuff?

    I've only got room for one PC to be rigged up at a time, and the other one won't do anything online, so yeah..I've got one, but I can't use it really! :)
  • I remember some stuff written for far earlier machines didn't compensate for faster cpu's .. so the games would run at stupid speeds.

    there are some nice ega games, yer I know the amiga blah blah blah.. but sod changing 14 disks on fate of Atlantis etc ;)
  • Haha! Yeah I loved Monkey Island 1 and 2, but there were so many discs it was almost as bad as multi-loading from tape :))

    IIRC CGA Star Wars had to be run in 8Mhz mode or something similar. If you hit the Turbo button on your PC (remember those?) and beefed the CPU up to a massive 25Mhz the game was an unplayable blur. Found a vid - not of the Turbo mode though. I remember it being a pretty good version.


  • People are right here. With each year and each new release of Windows old programs become less and less compatible. It's not only about DOS, some programs created for example for Windows 95 or 98 may refuse to run today as well.

    You were lucky that they ran on Vista but now, well I won't be original, just use Dosbox ;)

    It's the video driver model. There are various suggestions on that StackOverflow thread, including disabling hardware acceleration or loading an XP-model video driver.
  • Thanks for all the help and suggestions everybody..I'll try some of them out later! :)
  • I'm strictly a DOSBox bloke when it comes to DOS games (DOSBox plus a good frontend, such as Defend Reloaded, is very simple to set up, and to alter if a particular games needs a non-default memory/sound/etc setting), but some people prefer using old PCs so they can run the old games on period-accurate hardware.

    vogons.org

    is a great forum for collecting and using old PC hardware. Plus it's home of the official DOSBox forums, and also has lots of advice on getting old games to run on new hardware, and vice versa. It also manages to stay relatively free of trolls for some reason, perhaps because most trolls are young, and Vogons users are mainly older.

    Even 10 years ago, on Windows XP, i experienced some old Win9x games that refused to run because of the 16-bit / 32-bit barrier - one that comes to mind is Alone in the Dark.
    They were all budget re-releases though, so it was not a great loss ;)
