The VT220 emulation within MAME is just a skeleton, there is very little code behind it. I did some work on it a few years ago (along with the LK201) and I managed to get it to pass a few self tests but didn't get to the point of displaying anything on the screen. You might want to try the VT240 with the ROMs from archive.org: https://archive.org/download/MAME_0.209_ROMs_merged/MAME_0.209_ROMs_merged.zip/vt240.zip These should be the ones that were used to develop the emulator.
