Can't get backup PS1 games to play, Matrix Inf.

[velocity92c]

My backup PS2 games play just fine, but anytime I put in a backup PS1 game, the PS2 makes very weird clicking noises, almost as if the laser is hitting the disc, and it won't play. I've learned that some mod chips require certain button combos to get PS1 games to play but I can't find an instruction manual for this thing anywhere. Even using the swap trick with an original PS1 game isn't working (and it even works on my non modded PS2).


Any advice?

Hi velocity92c,

I know this won't help a bit, but let me tell you you are not alone about that. I also have my PS2 (fat satin silver, I'm not sure now if it's v10 or v11) with the original Matrix Infinity and when I put anything which is a PSX, I get the same weird clicking noises. If the games is not a backup, it works perfectly though.

I am not sure, it was a long time ago when I contacted MI Team about this problem, but I think they told me that 1 in a **00 PS2's of my version came with a manufacturing "defect" which didn't allow the standard MI chip to perform well with PS1 backups.

I have the same problem, so I'm going to bump this thread.

I have the same problem, so I'm going to bump this thread.

Bumping is fine for a thread this recent, as long as you don't do it too often, and only when you really are posting on exactly the same subject, like I think you are here.

As for a solution, I'm not sure what caused the problem to begin with, but I think that the MI chip always has had doubtful success at recognizing PS1 games correctly for booting. If that were not the case the programmers would not have felt it necessary to add a manual command to enforce PS1 (or DVD-Video) booting, as described in the following excerpt from the readme of MI firmware v1.82 (the latest one I have handy in my archives):

FORCING PS1/DVD MODE: 
---------------------

- Press CIRCLE on joypad 1.
 (This option is only needed just in case someone needs to force the PS2
  to boot in PS1/DVD mode).

So in turning on or resetting the console you should press down the 'Circle' button on the gamepad and keep it pressed until you feel sure that the firmware has detected it. I'm not sure exactly how long that is, but if you keep it pressed until the PS1 logo appears you are definitely on the safe side, and if/when that works for you then you can start experimenting with how much button pressing is really needed (I expect a second will be enough, but do it the safe way in your first tests).

Best regards: dlanor

Thanks for the input dianor. I already tried that solution a long time ago when I first noticed that problem but pressing circle to force psx execution did nothing good since the cdrom started making those weird clicking noises and without detecting anything...

Yup, I had tried the circle thing as well with no luck. Are there no other solutions? I could play backup ps1 games with my old ps2 with the swap trick but when I bought the modded one I sold my old one so I'm kinda screwed. I even tried the swap trick with the modded one and it recognizes the original PS1 game but not the backup. I tried multiple kinds of CD-R's as well.
