Since you say that my build of 0.8.8 is much faster than your build of 0.8.3, it sounds like your build of 0.8.3 is an interpreter version (as opposed to dynamic recompiler, which you get when you add -DDYNAREC to CFLAGS). I've done an interpreter build so that we can test this theory - grab it from http://www.devrx.org/software/rpcemu/rpcemu-spoon-fjd-2010-09-27-interpreter.zip and let me know whether it's more stable than the normal 0.8.8 dynarec build. > > Q1) I think they all related to inconsistent RAM allocation and I wonder if > there still may be a problem here?

Command+F12 is now mapped to break. F12 by itself should open a command prompt (this doesn't work for me with my external PS/2 keyboard connected via a PS/2->USB adapter, but it works on my MacBook Pro's built in keyboard and my external Apple USB keyboard). > > Q3) Roughly every 2 out of 3 times I open RPCemu, the boot sequence stops > very early with an hourglass after the first 3 lines of text (that show the > processor and "Acorn ADFS").
