I, too, have been frustrated with the quality of vt100 emulation.
People seem to get cursor moves, basic attributes, and things right,
but when it comes to more obscure sequences....  However, VTERM III
from Coefficient Systems comes pretty close.

It passes almost everything, including 132-column, light and dark
backgrounds, scroll regions (important to me), all the attribute
combinations, all the keyboard combinations, and handles double-sized
and double-height characters reasonably.  They even have smooth scroll
slower than jump scroll.

The things that failed are:
	auto repeat off
	request terminal parameters args 0 and 1 (although identify
		and DSR 5 and 6 work fine).
	reset didn't do anything

If I just start the program and do the VT52 test, it runs fine.
If I run the entire program through, the VT52 test fails.  I seem to
remember this as a known bug in vttest, though.
