[B2-devel] Re: Any use of MMU emulation?

[Gwenole B. <gb...@di...>]

Hi,

I was wondering if B2 would benefit from MMU emulation. Some users want it
because:

1) It enables the use of virtual memory.

My opinion is that if a user wants X MB of virtual Mac memory, where X >
physical memory available to the host system, he can already do so. The
host system will handle much better extra memory than letting MacOS
swapping to the hardfile.

2) It enables other systems to run under B2.

This is a false problem. B2 is "only" a Macintosh emulator and doesn't
emulate much of a Mac hardware. So, if B2 were to have MMU emulation,
Linux or other systems will probably not work anyway.

Other ideas?

There are currently two MMU implementations available on top of UAE:

1) One located at Bernd's website for UAE:
<http://www.freiburg.linux.de/~uae/bin/patches/mmu/uae-0.8.20.2-mmu.diff.gz>

2) The other included in ARAnyM (Atari Running on Any Machine):
<http://aranym.sophics.cz/index.html>

The latter is the first ever project I am aware of that is based on
Basilisk II. ;-)

Bye,
Gwenole.
