I am posting here my updates about my attempt to have the AES multi working. We were suspecting that due to some power deficiency of the PSU, the big games cannot be launched properly. So by launching some small game only I should not have any issue and that could confirm about the PSU problem.
I downgraded the firmware to r966, installing first the FW, then the menu_0401. I installed first Andro dunos in slot 1, no problem , then on the same slot I removed and add brazing star, it worked as well, then on the same slot I tried to add wind jammer, gave the black screen , switch of the console, wait few minutes then brazing star was still on the microsd , I tried to remove and add andro dunos again but it did nt worked (black screen).
Before also from andro dunos on slot 1 I could not remove it and add samurai spirit 1 on slot 1.
Then I upgraded the fw to the last one r1169 then the menu 1122. I add andro dunos on slot 1, it worked but then impossible to remove it and add another game, pulsar, blazing star did nt worked. I tried next to remove and add B star but the black screen appeared again. Then after restarting I could notice no game was installed some the removal worked !
Then finally I downgraded to r1110 (which worked form me in november 2019) keeping the menu 1122. With the new PSU I could not install any thing including andro dunos, and with the old one (see the picture upper) I could add android dunos on slot 1 but nothing else on the same slot.
Do you have any suggestion ? It is not clear that I am facing a PSU problem
