1) It gets hot after being on for a while. Maybe not burning hot, but hot enough to tell.

2) It has three connections: The back is a metal ground, usually the width of the regulator to varying heights. Then an in and an out, occasionally with aground out the front, although it's trimmed on some/most because it's redundant.

3) It's a black square, about 1 cm squared. Look for that.

I know what the 7805 is., and how to use it. I was just saying that I wasn't using a ps1/zenith screen.

And I'm saying that you'd be much better off pulling 5V from the DVD screen to power the SuperJoy 3 than running it from the batteries. It'd be much more reliable. You're new, I'm starting from square one. Sorry for helping...

(Also, this DVD Screen can accept A/V in, right? An analog signal. And you're sure the guts that accept it aren't integrated in to the motherboard of the DVD Player instead of just the screen, right?)

yes it accepts A/V in. If you look at one of the photobucket links I posted, It has Mario playing on it.

Well, I am going to have to wait until I continue on the electronics side. I accidenly succeded in ripping a microscopic trace on the main board clear off. I'll have to buy another sj3 now.

Just solder a thin wire to both sides of the trace and you are in business again. I had to do this once.

I should have mentioned before, people are saying about using 5v for the PJ3 - you will notice that your SJ3 takes 4 x AA's and doesn't like rechargeables? That's because it needs 6v. Lower than that and the video can be garbled. I tried it before. 5v isn't enough, although the amperage is fine, plug'n'plays I tested were about 220mA or so.

That is why these units are happy with 7.2v Put it this way, the plug'n'play carts I made before all needed 4 x AA's and all run happily off 7.2v Li-ions.

Not surprisingly. Fresh alkalines can easily be over 2V each.

Well, I tried several tiems to fix the superjoy, but could not repair it....So while I wait for a ne sj3 to arrive, I will be thinking of a name. Since the portable is using a pirate famicom, re-used "green" parts, and a clamshell style dvd player case, I would like to combine the names. So far I have "Famigreen", "Famiclam", or maybe "Famboy". Any ideas? Also what is a good paint color that doesn't show mistakes easily?

I kinda like Famiclam.

And paint it a bright green. Hides flaws rather well, with my experience.

I was thinking of painting it green, but didn't know how well it looks. Thanks.

OK the new sj3 came. now I have a question. There are two boards, the main one, and the one with controlls. What do each of the pins on the main board(the ones that lead to the ribbon cable) do? I want to bypass the controls board to save space.

themadhacker · Post by **themadhacker** » Sun Nov 16, 2008 10:53 am

bump. I think Ben left out the second board

themadhacker · Post by **themadhacker** » Sat Nov 29, 2008 7:17 pm

I have a problem. the crappy ribbon cable on sj3 is detatched. I forgot what side the two boards are facing when connected. can somebody post a pic of the two boards connected?

No pic, but the cart slot faces up, and the controller faces up.
When put in the case the ribbon cable folds
I dont have one anymore to show a pic
