I took a look at the code and you added a comment about yielding in
the scummvm part. You are right it would be better if i don't have to
wait for the scummvm but how to yield here? since i need to give back
a list, or i don't get the list of games? Or did I understand
something wrong?
roms does not return a list, it creates a menu and that can wait. The
return itself is not used. I can do that if you want.
ok i just start a new Process and create the menu when it finishes.
I tried to look how to disable a joystick plugin if it was running but i
couldn't get how i could achieve this. First I would need to check if a
joystick plugin is active if yes i have to stop it and restart it when
the emulator is finished.
What I have seen so far is that I can activate and deactivate a plugin
with plugin.activate and plugin.deactivate. But how do I check if a
plugin is running? Do i just use getbyname? Would you use
plugin.activate/deactivate or add a method to the joystick to let the
plugin release the interface?
thanks
Mathias
