Broken NES dogbone controller - how to fix?

[AdamAnt316]

Hello everyone. A friend of mine has a couple of NES toploaders, complete with dogbone controllers. Unfortunately, one of the dogbones recently stopped working, for some reason. Best I can tell, none of the button presses register at all. The contacts and pads are clean, and the cable has continuity. Might there be a way to fix it? My guess is that the chip might be to blame; I figured I might try and swap chips between the stricken dogbone controller and a standard brick controller, but the chip used in the dogbone is surface-mount compared to the standard through-hole type in the brick. Is there a known source for the surface mount chip these controllers used? If not, might there be a way to adapt the through-hole version for surface mounting? Thanks in advance!

Read the text off the chip and I can check to see if there is one.

The pins can be bent but if you aren't experienced in this it is as easy to break them off as it is to set fire to gasoline.

Here's the text from the top of the chip:

T 94 15H
4021BF

The 'T' is larger than the rest of the text on top of the chip. Guessing the 94 15 is the date code.

4021BF is a standard IC part number, it is called an 8-stage Static Shift Register.

Good to know. Do you happen to know of a source for this particular chip? So far, I have yet to find a source which sells just one. Again, thanks!

Kinda pricy. There might be something out there that serves the same purpose but is a different part number but my brain has had all of three minutes to function.
