You can run windows 3.1 in dosbox if all you want is Tetris. There's display drivers for large screens (or 24bit color, but not both) available for dosbox as well. A full virtual machine seems a bit overkill when my entire small doswin games directory is <200mb (this includes all WEPs and a few dozen other small games for win 3.x and dos). For better compatibility with the (extremely rare) program that doesn't work under dosbox's dos emulation, you can go further and run an actual copy of DOS on a disk image.
