First you get a some nice mod chip, I got a Modbo 760 one. Then you take your poor PS2 and disassembly it. If you did not want to write it off right away, then you take a look into this guide - in fact it was very simple, however from the second time on - http://www.rpghry.cz/dds/nastenka.htm#ps2
Now using the included both sided sticker attach the Modbo chip on the bottom side of PS2 PCB that way, so it's little contact match perfectly against where they connect the pins GND, M, N, O, P, R, V, U, T, Q - simply this way:





And now use your soldering iron to make a connection there, as shown. I used my trusty old transformer soldering iron, as I need to heat-up the PCB a lot to make these contacts possible:



It is not easy, but if you have a small slim soldering point, lot's of resin and just the good amount of tin on your soldering iron tip - it will work. Then check the connections with DMM, if they did not just look as conductive, but if they really are. Pin W you have to connect by wire and differently a bit. In the guide for Modbo 760 chip there: http://www.picsystems.net/diagrams_ps2/mod..._760_v12_13.jpg (backup link here: http://img118.imageshack.us/my.php?image=m...760v1213of0.jpg ) is mitake. You cannot get the pin W connected bellow the small white Modbo PCB board, so you have to use different connection that suggested. (in theory you can, but then the height of the soldering and wire will prevent connecting of the other pins) This way:



Then only a "fun moments" awaits you with soldering connections like the B, G H and I connections:



To show how small they are, I add a ruler there. In Centimeters, the small ares are millimeters...



Good luck!
Another mistake in the guide is, that instead of pin S it shown pin SX (!) - so just connect the pin S on Modbo 760 (new revision?) to the SX connection in the picture shown. Things work that way. Another problem is, that where to connect the pin Z is completely unknown to me ATM. Luckily this one is optional, so, it is not need to be connected at all. You just missing the features called "AR Max" and "Gameshark"... I have no idea what they even mean, so...


So then, if everything works as it should, you get only more fun now
Details, as the PS2 sold for Region 2 (Europe) can now play Region 1 DVD's such as only in USA sold Redux edition of Apocalypse Now:



...is perhaps not even worth mentioning. I tested the classis R2 (Europe), R1 (USA) and R4 (Australia) DVD's and everything worked w/o a problem.

At the start, there is a slight change in the PS2 logo:



And when powering PS2 off, there is this:

Sony must be definitively happy

Nice! Micro-soldering is a ######...which is the main reason my PS2 is still un-modded.

sorry trodas we dont allow talk about downloading games (ie piracy) so i removed that last part and the rest is ok!

Nice mod btw!

Nice!

I've got my PS2 modded with a solderless (EZI) DMS4 chip + toxicOS (I had to get it from like...Austria, they can be kinda difficult to get). I slapped in a 500gig harddrive and run everything from there (but there are some that have special security stuff in them like GT4...so I still have to get the disks out sometimes).

I need to buy more games, my harddrive is only half full!

put a damn shirt on please

It gets hot with a soldering iron!

oh i thought this was about how you killed it with a modchip like i did back near the launch of the ps2. man was that a bummer.

neddamttocs -

Ops, sorry. I just need something to test the chip on - you know - originals will still (sometimes, the DVD of GT4 I got to test is scratched badly and it become unreliable...) work fine, so...


Thewacokid - that is why I named the thread "How to kill PS2", because if you try this, well... you kill it. Very likely. It is kinda hard to do. These PCB holes are VERY VERY small (check the ruler, this big one are 1cm not 1 inch and the smaller ones are 1mm each!) and NOT SUITABLE for soldering.
It is almost like when you look badly at the small cables, then they break up from the PCB by themselves...


Crazy_Nate -

WoW, interesting.


QueenzPCfreak90 - sorry, but it is very HOT there todays, not to mention with soldering, so... besides, your monitor is overbrighted. I barelly see myself Got a reliable CTR that did not distort the shades, like LCD does...


hornybluecow - exactly my point. It looks now easy on the photos, but... try it and your PS2 is likely to end in silicon heaven
