PS1/2 Mod a Phat PS2 with nothing ?? is it possible

scousethief · Jan 17, 2011

Hi magsor thank you but the chip is completely different

it is this one

http://eboxing.en.ec21.com/Matrix_Infinity...81_4038282.html

which is missing some of the points

Magsor · Jan 17, 2011

They are the same your chip is just missing F which is just DVDRW support(who cares?). RST is RE and SX is S.

EDIT : I was wrong i looked it up more closely and SX is S now I dont know where to Connect CX still looking

in a different place.

top right chip is the one

MODBO 4 has the CX solder point. Look it up you should be ready to solder up.

Is there any way to test the chip is working without a game ?

I wouldn't think so... if you are trying to play a burned game, it would only be tested with a bunred game, right?

a quick question for the PS2 pros here. I have a PS2 SCPH-79001 and I was wondering if this cheapo chip is the right one to get:

and if there is a diagram for it somewhere...

All the modchip on dealextreme will work. But be aware that it take A LOT OF SOLDERING SKILLS to install this in a slim ps2. As for the diagrams check out the links above from filetrip and skapps all those modchip are very similar one to another.

all soldered in , tested for touching wires with meter and all ok but no display ?

edit working but wont read disks including originals

Does it say matrix, or some logo when starting up? and does holding Triangle + circle then turning on display a settings menu?

scousethief · Jan 17, 2011

no just boots direct to the sony screen

iirc the r,v,u,t,q,m,n,o,p,w are the "bios" points, when they are installed correctly, it should show modbo, or matrix logo before the sony screen and/or be able to access the settings menu. you may also need to double the ground and power wire if your wires are small. The a,b,g,h,i,s wires are for the disc drive protection.

thanks ill go over everything again

How can you mod a PS2 if you don't have one?

scousethief · Jan 17, 2011

I removed the chip... but left the wiring to the main board attached and she fired up perfectly fine ??? possibly a dud chip ? ill have another crack at it tomorrow as its geting late now.

I can solder directly to the bios chip legs for points RVTQU rather than those little pads and it shouldnt cause any problems ?

Is point S or SX absolutely necessary ? is there an alt point ? none of the diagrams are very clear so i soldered it to the bottom edge of the top fuse/resistor.

I think i a going to have to find more accurate diagrams

This diagram has less pins connected , the Y in a different pad only the I is soldered to the reverse of the board etc

Magsor · Jan 17, 2011

I read that you have to have CX connected.
check this diagram

scousethief · Jan 18, 2011

There is no CX m8

I know. I am in a digital electronics course and have been soldering since I was 10.

It'll be a fun project for me. Thanks for the heads up though.

It is possible to have a defective/dud chip. I had a quite a bit of bad modbos and a couple of dms.

should be no problems obviously. Make sure the trace goes to the actual leg tho.

S is not necessary, S wire is for PS1 games.

so... what chip do you have again?
