For some reason I had a hankering for a hunk of Day of the Tentacle and downloaded the demo from LucasArts' website. It didn't go well I'm curious if anyone knows of a good way to run old DOS games without rebooting into something like FreeDOS (basically DOS-in-a-window)?

Some googling turned up:

I'm going to try this out and see how it goes.

work good

Cool -- Thanks ... The Sam & Max Hit the Road Demo actually works properly in XP without me doing anything. The only funkiness was a direct harddrive access attempt in the installer (which you could say "ignore" to) and the sound detection was a little funky. But once I set the music to General MIDI port 330 and the Sound Blaster to DMA 1, it worked perfectly. Kind of cool to see the old games again

I can personally recommend DosBox, it really kicks some serious ass.

It's tricky to configure right, but once you're past that learning curve, it's just amazingly cool.

By the way, earlier thread on the topic here.

Yeah wow -- this thing is pretty damn cool! The D-Fend Windows frontend is particularly handy as well.

If you want to play LucasArts SCUMM based games then use ScummVM.

How's ScummVM do with Roland MT-32 music emulation (if at all)?

No clue. It does have MIDI support though. I think it defaults to just Adlib emulation though.

Seconded for DOSBox(.app). Runs great on OS X.
