Ingenious! However, I've just tried that, and find that it leads to the
same error, as reported previously.

I don't doubt what you say, but I'm having difficulty in understanding
why it should work, since the 6.20 boot sequence soft-loads the 6.20 rom
image, from !Boot.Softload which, in this case, contains no rom-image.

Please try! I'm sure that many readers would be interested to know the

Tried those settings - same error message.


Hi Tony,

On my PeeCee now - I found I had an older version of RPCemu installed, so I 
updated to the latest then took the ROM images from my Mac (and the HostFS 
folder) and plugged them into the PC version. The only problems I 
encountered was the FontManager and Desktop were unplugged, for some bizarre 
reason (not sure it was to do with RISC OS 6.20).

Anyway, have got both the Interpreter and Recompiler (not sure what the 
difference is here) running version 6.20, and it appears stable.

Incidentally, my PC is a AMD Athlon 64 with 3GB RAM and ATI Radeon HD3200 
graphics running Windows 7 Home Premium - if that makes any difference. The 
Risc PC model emulated is the same as before.
