After some day's working i finally got nulldc working in Mala.
no esc key, just hotkey in Mala (ALT+F4).
and changed something in cfg nulldc so the game loads automatic.
Only when the emu started the mouse curser is back in the screen and i have to connect my mouse (again) or i will buy a wireless mouse for this.
i also have hide mouse curser (program) only without succes.
How can i solve this little problem???


here some pictures from the setting's in Mala:

I really don't know how i get those ''emulator presents'' , only i can say i am happy with it because now nullDC run's automatic in Mala.
esc key nulldc (i am using i-pac)

with this setup you can kill ''nulldc'' in Mala (ALT+F4)
So now only the ''mouse curser'' left, so if someone know's how to solve this little problem, that would be awesome.
Thank you,
