Soldered these two chips to about 5 new consoles. Symptoms are always the same: works just fine when I test it (few reboots, disc swaps). Then customer brings it home and after some time playing, it just stops booting the DVDs. Bootup logo shows fine, but backup copies are not recognized, only originals play.
Soldering is OK, since this happened a few times already. Is there some known incompatibility with these chips on newer PS2's? Consoles are PAL.
Duo3 seems to work OK, but I got plenty of these cheap modbos on stock.
