U8 Wiring

[ShockSlayer]

Also, you can wire the same controller data to players 1 2 3 and 4 and they all work. At the same time. It's pretty *Can'tSayThisOnTV*ing awesome. I will post a video sometime tomorrow.

I'm using a Rev. 3, so Imma relocate my U8 chip.

Don't bother with the bottom except for 3.3v.

It would be cool if someone could grab a NAND and try this before I get back to school Jan 8th.

 

[Bibin]

99% sure that U8 is just being used for data buffering and it can be bypassed.

When I get home I'll oscilloscope it up for y'all.

Blurrughg, I have my scope here now and no N64s to play with :/

Bump for progress:

Now we can remove the U8. Beta told me. I soldered it .

I don't see the point in removing the U8

You can make the N64 smaller. Also, the PIF is easier to solder to.

Is it 100% compatible? Do all controllers work with all accessories (rumble pack, memory pack, transfer pack, GB slot)? What about player 2, 3, and 4 data?

Not really. The U8 is right under the PIF which means cutting the U8 section off gains you nothing.
Any who, it doesn't look like you've even removed the chip. Remove it and let me know if the controllers still work. I'm not holding my breath though

As far as I know, standard controls work. I've cut off the exp. pak port on the controller so I cant test any of that. If someone wants to test that, that would be helpful.

Eh, It's just general information anyway. I'll keep looking into it.

The n64 will boot without it, but controllers won't work without the chip.

But what do I know

 

[βeta]

Well sheeyit, I have tried that before unsuccessfully. I am testing ASAP.

So, it turns out the reason that works is because PIF-15 is common with the P1 data pin on the U8. Wiring just to PIF-15 won't work if the U8 isn't present.
