Thanks, its working now.
Unfortunately Im not particularly familiar with RiscOS, nor Arcem, so Im a little blind here.
Something doesnt seem quite right though, its pretty slow, but "feels" like omething is holding it back.
I ran !Sick, which took about 5 minutes to complete, and reported back that I have a 2.9ish mhz machine @2.1mips per mhz.
The whole time the cursor flickers, and it just feels like its struggling.
All sounds reasonable and one would think that it's simply pushing the host hardware, but something about the "feel" just didnt seem right, so I decided to run a 640x480 divx file at the same time and rerun arcem.
Lo and behold the results where pretty much identical.
Any tips please on how to assign more resources to the emulator?
Oh, and Im running it on my amithlon box by the way (core2duo@3.86ghz/dual channel ddr2-1066/matrox g550/sb audigy).
