Ah right, have just checked and the same issue is present over here. It appears that ArcadeSim is unable to start the'hack dll' I wrote to inject functionality into MFME. I wonder if it's to do with Windows antivirus having changed and it now sees the dll injection as a potential threat:
Thanks for the info, I suspect it's something Windows antivirus has started doing.
I'm a bit under the weather for coding at the mo, hopefully I can figure a workaround fix, so we can keep ArcadeSim working to tide us over until Oasis... I'll look into it hopefully soonish, fingers crossed I can find a simple fix, without needing to try build an ArcadeSim update, since the codebase it pretty much 'retired'... would like it to keep working though for the next 1-2 years if poss!
