Can you identify this mod chip? [PIC included]

**dromede** · 03-20-2010,04:39 PM

Hi there!

Recently, i acquired an old fat ps2 Ver. SCPH-30004-R. It's laser is half dead, it wont read original or backup dvd's but it will read any CD without a hitch.I tried cleaning it, angle adjustment, voltage adjustment... Nothing helped. However, it does have a modchip. Here's the modchip that i would like to identify:

The big chip is a Xilinx XC9572XL. If i want to boot backup PS1 games, i have to press reset twice. I tried booting backup PS2 CD games but it wont read them saying "Please insert PS2 or PS1 disc". it will recognise PS2 CD backups as PS2 discs in the browser but it will not boot them. That's all the info i have, i hope it will help.

@dromede:
With the extremely limited backup capacity you describe (no DVD, and CD only for PS1 games) that modchip is doing more harm than good as-is, regardless of its identity.

If you are able to do it safely I suggest you remove it completely, and then you may be able to retrim the CDVD player to read DVD discs again.

Regardless of whether you remove that chip or keep it as-is, your best bet for using that console for PS2 games is to get "Free MC Boot" (aka: FMCB) installed to one of your MCs, and use it to launch homebrew game loaders, and especially "Open PS2 Loader" (aka: OPL).

That will allow you to run games from USB drives and if you get hold of a network adaptor you can also use OPL to run games from a PC over LAN, or from an internal IDE HDD in the PS2. Either way, using any of these three media, you will be able to play PS2 game backups without using any physical CDVD discs.

I am inclined to agree with dlanor on this. The chip is causing more problems than any good it will do. Just looking at the high resolution shot of it, it's poorly constructed with legs of the main chip soldered together. My opinion of this is to remove the chip and at the very least, borrow a friend's same region PS2 to install FMCB on your memory card.

And just as dlanor says, you can use Open PS2 Loader to boot games via USB, SMB, and when a new version is released, internal HDD.

FMCB is what i intend to use, but i dont have a memory card yet. I was hoping i could use usbadvance to boot games from usb until i get a memory card, but usbadvance wont boot aswell. Probably has to with macrovision or something... I have no intention of using or repairing the CDVD rom. I just wanted to know what mod chip is this. I wont remove it if it will not interfere with FMCB. As i understand, modchips arent much useful today if you take FMCB into consideration...

i havenot read your post ver well but if its read cds then why dont you install FMCB over CD and then remove the chip and enjoy the USBA or OPL or SMS anything

**dromede** · 03-20-2010,07:05 PM

As i said, i don't have a memory card yet. Can FMCB work without one?

**Bootlegninja** · 03-20-2010,07:24 PM

No.

He also said that he is currently able to boot backup CDs only for PS1 games, but not for PS2 games, which also implies that it will not work for PS2 homebrews. So even when he gets an MC to install FMCB on, he still can't do it by just booting a CD-R.

His best bet is if he has some friend with a properly modded (hard or soft) PS2 to perform an FMCB installation on, or else to send an MC to one of the FMCB installer volunteers.

@dromede:
Don't even bother trying to do anything PS2-related without an MC, as that is entirely pointless. Not only do you need one for gamesaves (it is the ONLY gamesave medium of the PS2), but you will also need it for proper use of most homebrew software, since nearly all of them rely on MC for some configuration files.

Proper use of a PS2, either for game-play or homebrew use, is just not possible without an MC, especially as FMCB can ONLY boot from MC.

Yes, i understand that MC is essential. i should get one in a few days. Now about the chip, how do i remove it? I was thinking of just unplugging the two connectors and cutting off the white wire, is that safe?

And yes, i do have friends who can prepare my MC.

Do you think that the mod chip is to blame for DVD's not being read? The first owner said that they only played PS2 CD games on it...
