VisualBoyAdvance Emulator please help!

[StonyKid]

When I'm playing a game and press a button, the emulator sometimes doesn't do so(in game)! For example, when I'm playing super mario advance 2 and I need to jump and I press the a button(z key on keyboard) it doesn't jump! I have to press it a billion more times and it jumps (when it's useless) after I lost my mushroom powers!! Please tell me how to fix it!!!

Did you check if your keyboard is working properly? open the notepad
and type the letters on your keyboard.

How the hell am I typing correctly right now? Seriously...

Are you playing on a laptop?

[StonyKid]

Noooooo.

Try going out and buying a gamepad, it makes things a lot more managable, perferably with joysticks on it for the newer emulators.

Anyway to fix it without using money??

Go into control panel in windows and check the repeat rate for your keyboard. Might be related to this or you might have something like Sticky Keys turned on.

Also try mapping jump to a different key, and see if it makes any difference. If all the other keys work fine it definitely sounds like its related to your keyboard or perhaps specifically just your Z key.

Have you tried using a different game to see if the same problem occurs when pressing the 'A' (z) button?. If its ok in other games then the issue is likely related to the SMB2 rom. If it suffers the same problem in other games then the issue is definitely with your keyboard.

Ok, if it ends up being related to your keyboard and you don't want to go spend money on a game pad then simply change the controls and you'll be fine.

FatTrucker: I tried it with WarioWare.Inc and there's the same problem. Except now the d-pad also messes up. I'll check that repeat rate thing. What should I do to it?

Cloud: Yeah, I tried different keys and it works for a little bit but starts to mess up again.
