Ask Slashdot: DOSBox, or DOS Box?
An anonymous reader writes "Are DOS game emulators like the highly-respectable DOSBox good enough now, or is there still no substitute for the real thing? Like a lot of Slashdotters I'm getting older and simplifying, which means tossing out old junk. Which means The Closet full of DOS era crap. And I'm hesitating — should I put aside things like the ISA SoundBlaster with gameport? Am I trashing things that some fellow geek somewhere truly needs to preserve the old games? Or can I now truck all this stuff down to recycling without a twinge of guilt? (Younger folk who didn't play DOOM at 320x200 should really resist commenting this time. Let the Mods keep them off our lawn.)"
We're better off with DOSbox, emulators tend to last a lot longer than physical hardware. Plus we can just keep layering emulators (DOSBox in Linux in VMware on top of whatever comes next).
Not for DOS-era games, but the ones that came just after that (Dungeon Keeper 2, Roller Coaster Tycoon, Need For Speed 4, etc)
I've spent a lot of hours trying to get those games running reliably in a Win7 environment with no success (compatibility mode, virtual machines, etc).
Lacking any modern computer hardware until around 2007 or so, I feel I can relate to you, despite being one of the younger folks here. I grew up slaughtering hordes of Nazis in Wolf3D during the PS2 era, along with saving chicks with Duke Nukem, then getting my nerd on with Shadowland (I think thats what it was called :/). Anyway, I have a strong nostalgic love for these old DOS games, and I've yet to run into a problem playing them on DOSbox (Under Linux, just fyi). However, instead of tossing all that retro goodness, I'd put it up on ebay. You'd make a buck or two, and some other nostalgic fanboy will wet himself in joy. Everyone wins!
It's that word. "Closet". That says it all.
The question being asked wasn't "should I get rid of all of the fun stuff I use every day that's sitting in my entertainment room?" Instead it was "can I throw out my unused crap that's all in storage, neglected?"
All that stuff about emulators is just a smokescreen. You're not playing your legacy DOS stuff now, you won't tomorrow, and the day after that you'll be dead. It's a real trick to recognize when you're saving stuff because you have sentimental value attached to the memories, not the stuff itself.

Get a copy of VirtualBox for Linux or Windows and fire up the ISO download. I doubt FreeDOS can read modern SATA drives so running it through a virtual machine is ideal. FreeDOS is the most MS DOS compatible OS. Not to mention with virtualbox you can share files with a shared folder. I do not know if the guestadditions for Dos are available as I use Linux under it but it is worth a shot for sure.
What is great about FreeDOS is it comes with a TCP/IP stack and gnu tools like gcc and a nice editor so you can at least transfer files and old files from the internet to it to have the old experience back if you want to run DOOM shareware for example

While you can certainly install DOS on most VMs, the problem isn't the CPU being emulated, but other hardware. And even the CPU isn't being directly emulated in most VMs like VMware or VirtualBox, but rather utilising virtualization tech on your main CPU, but I digress - back to the hardware issues.
Sound in most VMs, for instance, is a virtualized AC97 or similar codec. Sure, there are some 16-bit and virtualized sound drivers (in VMware) for instance if you want to install original OS/2, but predominantly what we're talking about is a software-driven sound card as opposed to an entirely hardware based controller. If you've been around a while, you'll recall the difference between real modems and "win modems". One can be polled directly via its own interrupt/DMA (the real one), and the all the others sit on IRQ11 (not necessarily true, example) and wait for a higher-level driver to sort out what goes where.
DOS relied on "real" sound cards with addressable interrupts, etc, which simply aren't emulated in almost all VMs. DosBox does, emulating almost every function of the actual chipsets of SoundBlasters/Adlib/GUS/etc. It's exactly what real emulation is, as opposed to virtualization. VMware, VirtualPC, VirtualBox etc, provide virtualization. DosBox provides emulation. And there is a difference. :)
Likewise, CGA, EGA, VGA cards. Most virtualizers provide a VESA compatiable SVGA driver(think, an S3 Virge, or similar). DosBox actually emulates the individual functions and quirks of the different graphics adapter chipsets. CGA for instance, isn't just "4 color graphics, 16 color text". It's a very broad specification, and DosBox has to emulate how each aspect of that specification can be used, and abused, to provide the various graphical effects that programmers coaxed out of the original systems, and graphical trickery.
And most virtual machines don't support protected run-time mode, which you can look up. :) I've written enough already!
So yeah - you can run DOS on a VM. You just can't play many games on it. :)

My god man, who cares if he gets rid of the stuff if he's only got around 2 days to live!!!???
