Since the original can't be fixed, then fixing any emulator will mean that it's no longer a true emulation. Given how long this bug has existed, I think that should be left as is.
Well, at least the alternative ROM images could be made available alongside the original images. There are also patched images with support for 192 or 224 registers (instead of 64)...

Ideally, but it makes sense only for rather local and short patches and requires some special-casing in the emulator, patches could be dynamically inserted and removed by a flag user-configurable in the emulator.
