Is there a reason you're using goplat's emu for 84+ emulation? If it's anything non-nspire specific, why not just stick with wabbitemu or the like?
The only reason I see is if you're a linux guy like me
I can't help you there. I don't emulate calcs much.
Edit: Besides, it seems like my real nspire does that too, so are you sure it's the emu? (JK)
