Help fix a N64 Rumble pack

Hi.
I just got a N64 Rumble Pack as a "gift".
It's a used part. I could not make it work with any of my joysticks.
The only games that I have that supposelly support the rumble pack is Starfox and 007 Goden Eye.
I've already tried to use new batteries and clean the rumble pack and the joystick connectors.
I also disassembled the rumble pack and took a look at the circuit. Tested the diodes, fuse and transistors and all seemed fine.
I tried to draw the schematics in ascii art too.
It's fairly bad done and incomplete, please, feel free to correct any mistakes, add component values or even redraw it on a better way.

Code:

Any help on this will be welcome.
Thanks in advance.

 

Have you checked to make sure power is going through the rumble pack?

 

From battery yes, it's going through the fuse.
I just need to take a look on the power from the joystick.
I'll check it out and post the results.

 

Have done the test just now.
Yes, the Rumble Pack is receiving 3.3v from the N64.
Can somehow I make a device that tests it?
It has only A14 line and 8 data lines and the control lines.
Can someone explain me how this hardware is supposed to work?
I found some info, but it explains the joystick communication to N64.
Maybe I did not understand it fully...

 

Honestly, I don't know too much about the rumble pack. I know you can desolder one side of the resistor and solder it to one of the pins so that it uses the controller power instead of batteries. Also, I'm sure you probably know this, but, to check if the actual motor works, a simple AA battery to the 2 cables (the red and black wires) makes the motor spin.

 

Yeah, I've put on a 5v PC power supply and it spinned nicely.
I'll try the internal power mod.
By the way, the component on many tutorials I saw telling is a resistor is in fact a fuse, I think it's 850ma.

 

Ah ok, fair enough. Guess it makes more sense for a fuse rather than a resistor, considering it's only taking 3volts from the batteries as it is.

EDIT: @Fisher

Just found this website. Have to access it via the web archive. https://web.archive.org/web/20050322030836/http://home.t-online.de/home/stephan.hans/n64.htm

 

Great!! I gotta try to build this circuit to test and post the results!!
Many thanks!!

 

I believe when I did it that I went the route of just desoldering the existing component and moving it to the appropriate solder points
