Sounds like you might just need a better power supply going into your beige
box to help with the dodgyness.

The screen position in bitmap mode can be twiddled with via the bg2
scale/rotate control registers, can it not? You might just have these set
badly on the emulator unit but by some miracle they are fine if you run it
from a flash a cart.
