PS1/2 PMAP doesn't ask for dual layer DVD?

[Fien]

I tried the PMAP program on my SCPH-39004 PS2. It does read (burned) discs, but it's not at it's best.

To use it, I followed this post:

Using the calibration tool I can't get the jitter lower then 3100-3200 which was the original position.

Then at step 33 I put in a single layer DVD, a original PS2 game. The program spins the disc for a time, gives "DVD-SL FE LOOP GAIN NG: 101" and returns to the main menu without asking for a dual layer DVD.

The PS2 still plays discs, but there's no improvement from before using PMAP.

What does the "DVD-SL FE LOOP GAIN NG: 101" message mean?

Converting that decimal number to hex, I'd say you're out of the adjustment range.

https://github.com/ps2homebrew/PMAP/blob/master/README.txt#L153C1-L153C37

Your decimal value, 101, which converted to hex, is 0x65, which PMAP's threshold at max, is 0x60.

So the laser is worn out heavily?
