The chip is the same.

That looks bloody awesome. I don't think I can do a mod that good. My only soldering practising I have, I soldered together a digg button electronic kit. a strobe like electronic kit and a psone console with the aladdin one chip.

I think i'll be ok though. you used a glue gun right? I presume its safe to use in a pcb, I think I'll just use electronic tape to make my wires look neat like that.

tbh after seeing the picture I'm kinda scared to try that gnd method lol. I understand your method now that I have seen the picture though.

You'll probably be OK as you say. :)

Yeah, that's hot glue and it's perfectly fine to use on the PCB of the PS2. Electrical tape is fine too.

The tip to get wires like that is actually very simple. Place your chip in the correct position on the motherboard (between the 4 copper ground pads at the far end of the board on slim PS2s or between the BIOS and drive controller (LB/BA chip) on older 'chubby' models. Solder all wires directly to the points shown on the diagram obtained from the mod suppliers website and leave them quite long (but don't connect them to the chip yet!) Now if you look at the board, you'll notice 2 or 3 main groups of wires (BIOS, C/DVD Controller and PSOne BGA wires). All you do, is group these wires together and lay them out 'IDE Cable style' and tape or glue them in place. Once they're bunched, its easy to group them, bend them into the appropriate place. The points on the chip are designed so that when you lay them out in this manner, the wire on the inside goes to the first point and the outside wire to the last point - and eventually looks like mine above. :)

Give it a go, take your time and I think you'll be pleasantly suprised with what you can do... :D

Hi, I got a diagram from the matrix infinity website. The solder trick you showed is on a slim ps2? I don't think you can do that on that version ps2. Also, on the diagram, it shows a point called the scex point, what is that referring to?

Hi,
Yes you can do that on a non-slim PS2, however the ground point is in the middle of the board as opposed to the edge. On a 'chubby'-type PS2, at the edge of the board is long exposed copper edge - this can be scraped back and the same trick used. Or, use the large copper pad at the top end of the motherboard (by the GH number which the diagrams will probably point to)and run the wires down to the points below (though then your wires are then needlessly long).

The SCEX point is the wire used for PS1 backup authentication. Link that point to the 'SX' point on the top end of the chip. It is optional to fit it, however PS1 copies will not boot without it...

EDIT: Watch out on the diagram too - use the alternate A, B, G and I points (the ones not on the large BGA with fine legs) - don't connect two sets of wires to those points :)

hey, for the firmware, if I download the one on the matrix site, would I be able to play the backups of my games?

Hi,
Software to enable backups on your Infinity can be gained from the official software download page on the Matrix Teams website at:
http://infinitymod.com/cgi-bin/matri...inity_software

The DEV2 software is also listed at the top of this page if needed.

ToxicOS will not work on the Infinity - it is a DMS only firmware. PS2 mods aren't like XBOX mods where any BIOS can be used - it has to be specific to your device...

P.S. Have you installed the mod yet and it's working correctly?

not yet. I want to do the romeo mod first. I've taken apart the ps2. The romeo mod picture I had only showed where to connect the cable to for the v10 ps2. Not for the v9. The only picture I had for the v9 was this one
http://www.cyber-mag.com/station/laserV9.htm

that only shows the wire trailing to the hole. The solder points are for the v10 console. or am I missing something?

That's the correct picture and the one I would have directed you to myself. That 'hole' is what is known as a VIA - and you have several of these to do on the C/DVD Controller later in the actual chip install (wires B, G and I) as well as now when doing the Romeo mod - so 4 in total. The circuit board is made up of several layers, much like the floors in a house. Therefore, think of the VIA as the staircase which connects the various layers together.

This will take a bit of careful preparation to do correctly. Earlier I described the process of popping up Pin17 on the motherboard. Follow this to raise the leg into position - then we will prep the VIA.

Firstly, take a fibre-glass pencil and scratch the surface of the VIA so the copper underneath looks shiny as opposed to dull as it does now. If you don't have a fibre-glass pencil, use the flat of a Stanley blade *BUT* be careful! Too much rubbing down or if you cut the VIA it could be game over for the board or failing that, a repair job will be in order. Anyway, once the VIA looks 'shiny', coat it with flux to clean the surface of the VIA. Flux also makes the solder and wire apply much easier than without.

Now, take your wire and strip/tin each end. Solder one side to Pin17 of the LA and now take the other half of the wire. Add a little solder to it so it becomes sufficiently 'tinned'. Hold the wire to the surface of the VIA and place your soldering iron tip on the end of the wire. If done correctly, the wire should attach almost instantly. Otherwise, take away the iron and re-prepare the VIA as described above. Don't hold the iron on the VIA for any longer than a few seconds as it will either lift the trace (nasty) or melt the VIA into the board (very nasty and the end of your PS2).

If you follow this however, it shouldn't be too much of a problem. Once the wire does stick, give it a gentle tug to make sure it is properly attached. The wire can then be secured with electrical tape or glue (your choice). However, Before you continue, reassemble the PS2 and test that the tray still ejects etc and discs still read properly. If done correctly, you'll find everything is A-OK and the serious stuff can begin!

hi, on the alt b g and i points, i can't get the wire to stay on that tiny hole. the diagram makes it look a lot bigger lol.

i try to get some solder onto it, but the solder is so thin that it seems to disintegrate or maybe stick onto the tip. Just doesn't stick to the board. I don't think i've damaged the points luckily, but when I try and add the wire onto the hole, it doesn't stay there.

Hi,
Yep... those are the VIAs which are a bit awkward if you're inexperienced. Follow what I say above to do them - just be careful!

If you still can't do them, there's no point trying and trying until you ruin the board, so if that continues to be the case, you may want to consider getting a pro to install...
