Any higher value, or if you only have 320 ohm resistors, put two in series.

320 ohm resistor enough?

You mean to begin with? Most likely.

This is not the solution I suggested, but If it interests anyone it never hurts to learn! big_smile

Use google.

You're dropping from 6V to 3V I believe.

Well, no. The tutorial describes connecting it to both the +5v regulated pin and to ground respectively. The worry is actually current, not voltage. Current should be very similar in each case, but I cannot vouch for exact values at this time. If anything, I can imagine the DMG as having a larger current. Start with a 330Ohm resistor and either lessen or increase to another resistor value depending on the brightness.

Lead free solder? As nitro said, scrape off the old flux/gunk and the heat will flow more easily to the pre-existing solder points, melting them.
Pretty sure you can get a replacement pot from radioshack if you wanted to.

But seriously, what are you unveiling? :serious:

I can't believe others listen to this shit too. I thought I was crazy.

Make an offer. At this point, I just want it gone.

Looks like one of the RAM chips has been replaced at one point in time, considering the socket. In any case, the chips in the ebay link are what people suggest, yes.

These may be your best bet:

The chips are all out of production so a high price is to be expected. you will need to open it up though so that we can make sure of the board revision. Later models, of which about a quarter of my breadbins happen to be, have the smaller B. revision board. This has different IC's.

I'll open this thing up as soon as I get a free moment. Per the post on Amibay the guy said "Since you are ordering at least one new IC, you might as well order eight" which kind of lead me to think these parts were readily available...

No big deal though, I love a good goal to work towards.

EDIT: Oh those chips aren't badly priced, shouldn't be a problem. I'll take pics of the inside soon.

Exactly why I said to open it first. The rev A requires 8 of the chip I linked and the rev B requires only two but of a different kind. Most commonly though, you will have a rev A.

These chips are going to be hard to desolder because of he board thickness. You may as well just cutthe chips off at the board and then remove each pin one by one. Also make sure to install sockets.

I need the pinout of the gameboy pocket's CPU. I can research it myself, but if it has already been done....:)

I got it myself, thanks.

I'd be more than willing to commission you to repair it if you're willing.

Not me, I have had enough trouble from my own breadbins. hmm
I know someone else will chime though. Good luck.

It is the difference between a cold-boot and a warm-boot.

Count the pins on that "midi" cable. I am guessing it is not 5.
Also, one or more of your RAM is bad. Read through this;

My good friends at Amibay should be able to help. smile

Also, very good on you for finding that in a box! Really.

I also think that the added button is no more than a reset button, but still pretty cool indeed.
