We just flashed a fw with 80 games.
But the stick bug was still there.
Here is a video demonstrating how to test the stick bug.
The left direction is easy to trigger, but the other three directions are not.

We hope all the players should test your hacked NGM.

Out of curiousity, has anyone in the US has gotten the Joystick Bug? Everyone I keep hearing about it, has been from a European country, and if thats the case, I think im gonna buy one direct from Europe. I know they are the same as the US version (thats evident) but something's not adding up. I flashed over 40 yesterday from various people who wanted it flashed, along with my 3 Internationals and 1 Christmas Edition. I have yet to have seen this Joystick Bug actually happen.

Thank you very much, Sir. The method is to replace all the four 10K resisters by 5K. I got it and I will have a try.

But, why is it a hardware bug. I used to think it should be a software bug.

I will replace it as soon as possible, and I will let you know the result.

I am getting to know why it is a hardware problem, because there are at least three different hardware version of the joystick motherboard. Thus, the system config must be modified to adjust the prameter of the dead zone for each version.

That actually explains a LOT... the ones I've flashed all have just the ngm-v1.0 tag on it Also I have seen this in the actual mvsnjemu code:

Which i've worked to modify and i'm in the process of compiling. Also i'll open up my Christmas edition today and get you the controller of that as well.


Side note, i've also added in a bios selector, and controller config menu... if that works out, you may not need to mess with the controller hardware itself, so wish me luck
