I guess it has nothing to do with the MOS-Team not allowing access to the first KB of ram nor to use memory management functions...

I wonder how I ran Shapeshifter, Fusion and iFusion years ago now it seems we need Linux to run a Mac emu on a PPC machine

@Leo & Crumb

Neither Shapeshifter or Fusion would run if you had Enforcer or CyberGuard running on your Amiga and you had to run PrepareEmul to move stuff away from low mem.

In MorphOS it does not work. Low mem constains system private system stuff and PrepareEmul kind of hacks are no longer possible. Having an access to MMU does not help because memory is already used by the system. Special MorphOS build would be needed.

who is the this picture's autor ?

It's my desktop.
(Xami_rtg server connected to my SunUltra2 linux machine (debian) which is connected to Windows machine using rdesktop) :)

@itix

BasiliskII ran on the classic without using Supervisor mode so MMU stuff wouldn't be affected and Thor's MMU.library can run MMU apps similar to cyberguard and also move the first kilobytes of ram.

Yeah, current MOS wouldn't work, but changing the kernel loader to leave the first KB of ram free wouldn't be too much work.

Basilisk II/68k on Amiga uses PrepareEmul stuff. It is just Shapeshifter rewritten in C.

Thor's MMU lib was just pointless exercise and doesnt solve problems involved with non-PrepareEmul Mac emulators.

It is not about "kernel loader". There is purpose why low mem area is use.

Care to explain that remark a bit further?

It is useless to everyone except Thor who developed Mu#? tools using MMU lib.

@Itix: what kind of "MorphOS build" ? I mean: on a technical point of view, what's preventing it from working on current MorphOS ?

Leo.

Special MorphOS build as in customized MorphOS ISO image for you. Since low mem is used by the system it cant be occupied by emulators.
