The problem is, that the tilemap is too big for the rozvideoram. It is defined as 0x100000 in these two sets where all other define it as 0x20000.

Added additional sets from 0.159 testrun.

They all work if the ROM size is increased to 128kb.
Any idea why they were set at 64kb? Can we just increase to 128kb and go home?

Probably because there's only 64KB of RAM (not ROM) on those boards. Fixing the namcoic.c code to work with variable RAM sizes is the answer, not adding nonexistent RAM to the address maps.

this appears to be fixed in 0.162, but I haven't found the check-in that's responsible for it...

looks like it was fixed in 0.161, my local copy of mamed for 0.161 doesn't crash. Resolving.
