Hello guys,
Started a portable and finished the cartridge slot relocation but it does not work.
Checked for shorts im 99 percent sure their arent any.
ide cable 10 year old pc stranded.
Around 6ish inches long.
Any ideas?
also pm me if you want to send me a free 3.3 volt regulator!! :)
I have all other materials for it
 
The reason your cartridge slot relocation is not working is because you exceded the maximum wire length. It should only be around 4" MAX. I'd shorten all the wires to 2.5" because that's really all you need.

As for the 3.3v regulator, you can already get free samples from TI. Just sign up and click get free sample.

Here's the one you are going to want to use:

Oh, and welcome to ModRetro!

6 is the max. Not 4. Believe me on this one. It's what I do.

I've experimented with wire length. I could never get 6" to work, but as soon as I shortened them, the N64 worked like a charm. I think that it has to do with different mobo revisions.

But, whatever. Listen to Bud, he's the man. :dah:
 
I've tried again and again to relocate. The wires are now to about three inches in length with a few longer or shorter and it refuses to work.
What can I do?
Also in the meantime I wanted to know if super glue epoxy works well to bond plastic to acrylic so i can make the case.
 
Which set of pins are you relocating to? Are you putting the wires through the holes, or are you soldiering them to the outside row of pins? You have to scotch tape the wires (better than solder imo) to the outside row of pins no matter what.

The O is where you need to solder and the X is where you probably soldered.

If you soldiered to the outside row of pins, and it still doesn't work, you probably fried your board. If you so much as let one tiny strand of wire touch another pin, your board is most likely dead.

To answer your other question, I don't recommend using super glue at all. It is simply too brittle. If you want quality, use Epoxy (it will require a lot of sanding to get it nice and smooth). If you want a cheap fast case, use bondo and/or JB Kwik (it doesn't require as much sanding, but is smelly and usually ends up cracking).
 
I wouldn't trust the heat test because it won't get very hot unless you have something shorting. Don't worry man, we all go through fried mobos. As much as you don't want to, get a new board; sit down when you are in a good mood and scotch tape the wires (better than solder imo) to the outside row of pins.

Use epoxy for all of your gluing needs. Just make sure to sand it down until you have what you want it to look like and feel like. Also, I wouldn't recommend using acrylic because it scratches with sand paper and cracks way too easily when you are trying to drill or cut into it. If you are dying to have it see-through, use basic clear plastic, not acrylic.

I would suggest just getting a case from www.polycase.com and frankencasing it.

Best,
SQ
 
Do you guys think I should just skip the n64 portable for now and do a sega genesis as my first project?
I honestly dont think im experienced enough to do an n64 right now.
Besides I enjoy playing games without lag :D
 
I think if you can't buld a N64 Portable, practice on old broken toys or something. Unless you are trying to RCP wire, most of the wiring is basic soldering. I really don't like to be negative, but building portables isn't easy, and just because you can't build one with one game console, doesn't mean you can build one with another. Also, what the heck are you talking about? The N64 doesn't lag. :stare:

This. N64, lag? What?

And don't feel like I'm telling you to do this but, stick to the N64. You can do whatever you want, but the N64 is a great portabilizing challenge. Enjoy the feeling of attempting a difficult task, and don't give up!
 
Undervolting can cause slowdowns. Never had any lag issues. Xbox's lag more than N64's do :/ As for the board, I've found that N64's do not fry easily at all. You can easily tell if the board has a short: The LED. 9 times out of 10, the power LED will still light up, even if its fried. If there's a short (or the 3.3v line is undervolted), that LED won't turn on. Also make sure you have the Jumper/Expansion Pak in. Take it out and blow on the connectors or try a different one, because sometimes that's the problem.

Not sure how it has a low frame rate. If he thinks it does, why not overclock? :confused:

Meh. That'd be cool except the N64 doesn't have a crystal for system clocking. Sigh. :(
 
Incorrect, sony. The n64 has two clock crystals to be exact. Overclocking is pretty common for the n64.

Bottom right area. One for each coprocessor I believe.
