Ok, I have discovered that my problem with the controls, it is the fault of the bluetooth dongle, it is not 100% compatible. I already bought one from broadcom that if it is 100% compatible.
To the problem of the hotkey that I mean, is that for example, using the xbox command, I use the button with the xbox logo as hoykey, emulators like "snes, nes, megadrive ...) pressing hotkey and the corresponding button, I get the retroarch menu and from there I can go back to the emulestation menu, but ...
In emulators like "n64, wii, gamecube and some more", it seems that that button has no function, and every time I want to change game or emulator, I have no choice but to turn off the whole pc.
I've tried the emulator on my desktop pc, with an nvidia GTX970 and intel I7, and when they start emulators like dolphin, I see that the nouveau controllers start, they leave a lot to be desired, making titles like zelda, or the mario himself GC kart ralenticen ...., is there any possibility of forcing nvidia private drivers ??
The dreamcast games, I downloaded them in gdi and cdi format, but I did not get it to boot any, I always have the black screen (this happens to me both in the original pc with the i3 and graphics intel, as in The desktop with i7 and nvidia)
Greetings and thank you
