But is there a NewWorld ROM of 4 MB in size? I mean main_unix.cpp contains
a check to "abort" if the specified ROM in not recognized (TNT, NewWorld,
etc.) but then further checks its size.

Or is a 4 MB ROM from a PowerMac PCI needed then the one found on the
system disk overrides it when booting?

Could it be possible to use the UAE m68k emulator? Though there are
apparently some issues in doing so: how m68k exceptions are
triggered, handled and interacted with MacOS?
