Dolphin making progress.. someone just MIGHT want to have a look at this

[Karosa Alabaster]

QEmu seems interesting too..
found some threads on a qemu/mol idea
http://mail.gnu.org/archive/html/qemu-devel/2003-06/msg00184.html

also the qemu main site is http://fabrice.bellard.free.fr/qemu/
what docs contain about mmu:
For system emulation, QEMU uses the mmap() system call to emulate the target
CPU MMU. It works as long the emulated OS does not use an area reserved by
the host OS (such as the area above 0xc0000000 on x86 Linux).
It is planned to add a slower but more precise MMU emulation with a software
MMU.

About sheepshaver.. it seems nice, but 8.6 isn't really THAT much better
then 8.1 which one can run in Basilisk II
It's a nice effort though.
