Tested these games with FreeDOS 1.3 RC4 on VirtualBox, on Fedora
Linux. Tested with boot option 1 "JEMMEX, no EMS (most UMBs), max RAM
free" but I don't think it matters. Sharing my results:

Plays fine on VirtualBox.

The game runs in VirtualBox, but it's unplayable. The text fading
in/out is very slow (same as QEMU) but then my turn immediately ends
without anything happening. Another slow text fade in/out, and my next
turn immediately ends without anything happening. And again for my
third turn.

I pressed Esc during the fade in/out text, so I think that exited the
game for me. No errors on exit.

Graphics are weird on VirtualBox, using VBoxVGA. I did get sound
though, which was nice. When I died and lost the game, the game just
sat there at "Game Over." Didn't matter what keys I pressed.

Rebooted, played it again. Same graphics weirdness, played and lost
the game .. this time, it hung on the "Quit? Yes/No" screen.

Bolitaire runs fine on VirtualBox. I'm just not a fan of Freecell. :-)

But when I exited, the system froze. I had to reset the virtual machine.

I get a similar "Interrupt divide by zero" and a stack trace.

Plays fine on VirtualBox. But it seems very laggy, or maybe that's the
game. Either way, the game is not very fun for me. :-(

Plays fine on VirtualBox.
