@Thomas Richter « Exec now reserves 16K of chip memory for emulator business. You no longer need "PrepareEmul" or "MuMove4K" to run Shapeshifter and friends. If you need the 16K back, there is a utility on Aminet by now ("MoveLow") which restores the previous setting until the next reboot.«
I think it should be the other way around, if users want to use an emulator they should use a tool to do so, the OS shouldn’t reserve 16k this is bad design IMO. Can you reverse this?
