Lightning's FINAL PlayStation 2 Portable design
- Thread starter Lightning
- Start date
Latest render, this is beta 3
I have the EEPROM chip tentatively connected, I'm not 100% sure it's correct yet. The only traces I can't draw yet are the 24 data lines I still need the full datasheet, but at this point I may just buy a chip so I can get the bloody thing!!
Lastly, I'm open to name suggestions, any ideas a welcome!!

Sup yall!!
So my HDMI board is almost done, but still on hold. As a result I've been designing some minor PCB components for my portable, and I must say, I think this is gonna be my new thing!!
First up just a simple pass-through for the ribbon of my LCD. I was gonna buy one but they were all a little big.
Second a mounting board for the USB port and memory card. I'm going to cut a memory card port out and bend the legs up to make it a standalone SMD component.
Last, and probably the most complicated (it sure took a while to draw all the traces). I discovered that the old network adapter from the fat PS2 was essentially integrated into mainboard, chip and all, and the only reason the signals are pulled low is because they're usually unused. Conclusion: they can be removed.
So I'm going to use the original soft PCB cables, folded over at 45 degrees, without resistors, and my own custom IDE board:
I'll be ordering these boards in a few weeks, probably try and arrange them all tetris like so I can get them all in one printing. Perhaps now I'll make a few controller button boards.. Yea this is definitely my thing now

Man these boards look like they're gonna be awesome. Are you planning on selling prebuilt PS2 Native HDMI and PS2-IDE boards in the future? I know I would definitely be interested.
Hey lightining will this mother board fit in a laser doodle caseGreetings everyone!! (or at least those of you who still bother to check this section lol)
So as I said in the penultimate post on my previous worklog, I have begun working on a new design for the project, one which I feel is the best approach for the kind of device that I want to build, so with that in mind, I present the initial stages and work that I've done so far;
The idea, for those of you who pay attention, is actually one that I came up with for @PKSYHR, when they brought up the idea of portablizing a fat PS2, and I later realized that it was a far better solution than what I was building. What I am doing is using a GH-035-11 version 12 PS2 (70011), and using the Automan hard drive mod as a means to load my games:
I chose the GH-035-11 revision because of the single EE+GS chip, other versions use the more primitive separate EE and GS chips. the upside is less heat generated, and one other thing which I'm saving for the end...
Here you can see the bottom side of the board, the FreeMcBoot memory card (removable of course), the CMOS battery, which I was able to relocate to the bottom side using a holder from and old 79001 motherboard.
here is just a little demo of how I will mount the HDD interface board:
Now, the other thing I mentioned above..
Did you know that the PS2 is actually capable of crisp, high quality video? Anyone who's ever seen a PS2 game being run on a computer through the PCSX2 emulation program, will have noticed how significant the increase in quality is. The reason for this, is that like all game systems, the PS2 has a conversion and compression chip, which takes all that gorgeous video and tramples it down to a mere shadow of it's former self, blurry and just generally dissapointing. PCSX2 skips this step, hence the high quality.
During my research into the version 12 motherboard, I came across a highly detailed service manual, which shows every IC on the board, their respective pin-outs, and how they connect to each other... Basically a modder's wet dream lol
here's the link:
http://gamesx.com/wiki/doku.php?id=sche ... schematics
Anyway, this manual showed me, among other things, that the native output of the PS2's GS chip, is 24 bit Parallel RGB... a signal standard which is used by a great many LCD screens... So in a nutshell, what I am attempting is direct video, no conversion, no losses in quality, just an 800x600 LCD, and not a single pixel unaccounted for
Here are my tracings for the data lines:
My plan is to design and fabricate a small PCB to attach to the resistors that make up the Data signals, sort of like how the hard drive mod is attached actually, and then design a power driver board that will go on the bottom side.
Obviously this is a highly ambitious mod, and I would probably put my chances of success at around 10-15 percent, but if I pull it off... Well I've always wanted a mod named after me lol
sorry for the long post, they wont all be like this
It certainly must seem that way, I am in fact still working on it however, And I'm actually using the ADV7511 now interestingly enough.
If you wanna do VGA output you can actually get native VGA from the stock converter chip (CXM4XXX), just put the PS2 in RGB mode in settings, and grab H and V sync from pins 22 and 21 respectively.
Hit me up over PM if you have any other questions

But would that be a progressive signal?
I thought about that, but i think if you tap directly to the H and V sync pins it uses progressive signal.
If not maybe even try taping to the pins directly from the EE+GS chip.
I'm just guessing, i haven't tried myself, but i also think it wont work because in the Matrix Infinity menu when i enable VGA mode, my monitor says signal out of range which is 56 to 75 hz vsync and the console outputs 31hz in this mode.
Maybe it's in interlaced mode and my monitor doesn't support it.
I could use GSM, which I have used in the past but some games don't start with it.
Jak and Daxter: The Precursor Legacy, Jak II Renegade and Jak 3 are three examples of this case, but Jak 2 and 3 when i enable progressive mode in the graphic settings it works with VGA (or RGB/YPbPr) without GSM.
But Jak and Daxter: The Precursor Legacy even when i enable PAL (Non interlaced) in OPL+GSM it still doesn't work.

I do not believe this chip will work. The digital RGB is a 1.7v signal so you must use a dac with a 1.8v digital power supply. I used the THS8135. It probably isn't the best choice but it does work. http://www.ti.com/lit/ds/symlink/ths8135.pdf
On the datasheet of the ADV7125 in the electrical characteristics, it's says that the input supports voltages between 0.8v and 2.0v.
That means that an input is registered as high if the voltage is OVER 2v hence the 3.3v power supply logic. An input is low if it is under .8v.
