DOSBox Portable, a version of DOSBox that you can install on USB, was released a few days ago:

I just thought that you guys might like it. No affiliation whatsoever with the maker. Mods, feel free to remove this post if necessary.

Hm... I've been running DOSBox on my USB drive for a while now. :)

Here's a posting about it on the DOSBox forums (at VOGONS):

<div class='quotetop'>QUOTE(mirrorshades @ Aug 30 2007, 05:57 PM) [snapback]307842[/snapback]</div>Someone mentioned somewhere that you need U3 (or was it 3U) memory card. Is this just mambo jambo or can I use the ordinary USB memory?

ps. those U3 thingies are damn annoying btw

Works fine on my extremely cheap 2Gigs USB stick (Doesn't even have a brand name).
And I can really not think of any reason why it should be otherwise.

I mean, do you suppose the app will check what brand your sticky is????

And you always can simply copy the dosbox folder to your stick. Works fine.

Thought so.

I will propably put dosbox and firefox to my stick so I don't have to use this slow IE7 at work.

Added link to dosbox download links sticky. Thanks for the heads up on it!

I'm running it on my USB hard drive (no fancy U3/3U/3D/3M/whatever involved). Works like a champ so far. You can even edit the config file so DOSBos automatically mounts your DOS games directory on the portable drive when it starts...no matter what drive letter it's been assigned.

These Portable versions are very good. I've been using Portable Firefox and Thunderbird for some time on my USB hard drive.

Post plz! I'd like to set that up myself

Of course you realize this topic is half a year old?
