Looking For: Patch for Risc PC support for Acorn's software PC Emulator

In theory there’s a patch around that makes Acorn’s software PC emulator (!PCEm) work on the Risc PC rather than just the 3.10 era machines.

Does anyone have this patch?

As a backup, does anyone have a patched copy of the program?

Is that the patch that allows strong arm compatibility?
The PC emulator uses a lot of self modifying code so the strongarm would only work with the cache switched off.
If so then it may be the patch that I wrote.
I gave a copy of it to a guy named Max, who put it on his website. It used to be still available on the wayback machine, but I’ve just had a look and cannot find it. He rather usefully called the patch “jeff.zip” !!

I’ve found a copy on my machine at work and uploaded it to

Could one switch caching off just for the emulator’s slot I wonder?

You could, but then the emulator runs much slower as the key advantage of the strong arm is lost.
The patch just adds a few os_synchronisecodeareas in the self modifying bits.

Oh even better. I thought you meant you needed the patch AND the cache off.

Many thanks, got it working.

Now get RPCEmu working inside PCEm inside RPCEmu…

Recursion is fun, but try a hierarchy first: RPCEmu running PCEm running ArcEm running FasterPC running Archie running DosBox running…OutOfEmusError.
