non-zero VBR is supported here. But uaedbg complains about read at 0, 8, C, ... forever when my program doesn't read at those locations.
Zoned the program (galaxian.zip). Just start it, and see that uaedbg has hallucinations in memory violations.

It is bitplane DMA doing those accesses. 6 planes enabled but only 2 first planes have valid pointer. Unfortunately it currently can't report which kind of access caused the "fault". Only way is to manually check all DMA pointer registers (e command).
Any chip RAM access below address $0400 are always reported. (except long aligned, long sized exception vector reads)
