Hello, after my first great experience in the portabilization of console (O-Wii), I really want to make a portable PS2 !
So here is my worklog :D

Here are the ideas that I think to integrate :
Custom buttons PCBs with PS2+ on it + RGB led, power button, L1 + R1 (and maybe U-Amp on one side).
PS vita buttons and joy-con joystick
Kingston USB adapter
5.6 inch 4:3 screen
ZYPDS PD USB-C module
PS2 PMS
4 x NCR18650B or 2x 5000 mAh Li-Po
Very thin mackbook fan and I need to found good heat sink, I'm pretty confident on this side @Gman told me that the ps2 was heating up a little less than the Wii.

I have a slim model 79003 PS2 Slim thanks to my spanish friends @KaitoTV , thank you very much !

I have found a Free McBoot 64mb memory card on Ebay for 10€

For now, I am waiting for a PS2 Controller (5€ + 5€ shipping), to test if all work and install all I need on µSD card.
I have found a dead PS vita for 15 € + 5€ shipping, I would try to repair it, I think especially to use it to have the dimensions of the buttons and the space between each other.

Then I could trim the motherboard (advanced trim of course !)
After that I could model it in 3d (if someone already has the files it would help me a lot) to be able to have an idea of the space it takes and how I will organize my case and the PCBs I will create.

While waiting for all of that I have already started to make a first design on paper to have an idea of the real dimensions and to see a little bit the placement of each component in order to choose them as well as possible.

And for now I am Waiting ... :eyeroll:

None........Yet
I've modelled the PS2 board (advanced trim) and the free mcboot card. Both are in the link A-s6 posted.
ill be adding a Raspberry pi both both fully poputaled with components and with the components i plan to remove for my own PS2 build

For now, I have tested 2 screen One 7" 1280x720 16:9 and a 5.6" 4:3 640x480 :
I really don't know which screen to use, the 7 "has a better picture but the 4: 3 is narrower :?:

And yesterday I have Trimmed my PS2 and her the result :

I think I can trim it more, and remove some component, I am going to make question thread about that.

Last Night I have trimmed the board much smaller, a little like the Gman's GS2.

Her the result with all wire solder on it (color is the same as the guide) :

And the other face :

I just tested and unfortunately it does not work, the circuits heat up (I think the PS2 boot ? ), but nothing in video output ... o.O

This is the voltage I have measured :
3.33V
2.44V
1.79V
1.23V

Do you have any idea why it doesn't show the bootscreen ?
Voltage ?
Other ?

I'm pretty sure you still need to connect 5v to the ps2
Correct. You need to connect 5v to the AV chip, which oddly is not mentioned in the guide but necessary for video. I don't have my multimeter handy, but I believe it's right here that you need to connect 5v to. This whole trace is 5v I believe:

Great work so far! I'm looking at building a ps2 portable myself. Where did you get that 7" screen?

Edit: What extra were you able to trim off the motherboard?

What gauge wire is that? You should be using 22awg for the 1.25v and ground, there is significant current here and can result in voltage drop if thinner wire is used.

It is AWG 24 I think, thanks for this point of course it is just for testing now, it is not the definitive wire ;)
I think of using 22 or 20 AWG with Teflon insulation (reuse wire, not buy because it is very expensive lol ).

I have made some progress in the idea of design for my Portable PS2.
I think to use 6,5" screen, the 7" look to big, and I don't like the 4:3.
And for the battery I am going for two 5000 mAh LiPo of 75x55x10 mm, thank you, @Gman, for helping me with this part !

Here is the idea :

And for now I have replaced the fat LM317 by this tiny TPS73618 LDO for the 1.8V reg.
It is a little dirty, but it is stable (just tested the voltage output, not tested with ps2 yet) :

Tomorrow I will continue my custom controller PCBs, yes I didn't tell you about that now.
I will show you the result soon ;)
