Try swapping the ROM chips if you haven't… although I think that was only a
problem for 3ks. Actually, this is a stupid question, but are the chips
oriented properly? Also, somewhere in the dim recesses of my memory there's
something about GVP boards… you might possibly have to yank the GVP board,
install the ROMs, then put the GVP board back in. But hopefully someone else
with a better memory will read this message and tell you what's *really* up.
