Matrix Infinity slower loading for PS-1 games & Blue Led flashing 4 tim

[retroborg]

Hello,
I recently installed an official Matrix Infinity Green Dot Version in my PAL PS-2 39004 V7 GH-022.

The chip works fine and everything boots up, I even flashed the chip from v1.68 to v1.82 firmware.

However, I noticed that when I load PS-1 games (Either copies or originals of any region), it will take a few seconds longer to boot them up than it would with PS-2 CD/DVDs. I also noticed that after I insert a PS-1 CD, the blue led of the reset button will flash 4 times before it starts reading the CD. (It will not do this with PS-2 CD/DVDs)

If I disable the Mod Chip, the PS-1 original games will load faster and the reset button blue led will not flash 4 times, as it would when enabled.

I have no previous experience with Matrix chips, so is this a known characteristic of the Matrix Infinity Green Dot chip, or is there a problem with it?
Or is this simply how it’s supposed to operate on my specific PS-2 model?

Other than that, it seems to work perfectly and will load anything I throw at it.

Any info will be appreciated,
Thanks in advance.

I found it strange since the Mars II MA-502 on my other 50004 GH-026 model, will load the PS-1 games faster & the led will not flash, but the Mars III will not auto boot the games (need to press reset 2 or 1 times) and will not display the import PS-1 games in full screen like the MI does, so that might have something to do with the problem?

Technically, do you know why it the MI does that by the way?

Another mate also reported a problem after using a MI chip in his PS-2, when ever he installed a hard drive, the laser drive motor would spin like crazy over and over but if he would take the hard drive out, it would go back to normal!

But I have not seen this to safely comment on it.

By the way, is there a way to force the Mars III MA-502 chip, to display the import PSX games in full screen, on my 50004 model?

Thanks in advance.
