Dolphin crashes when I try to boot my Nand copy (and a doubt about importing saves)

[Intruso]

:I have a good copy of the nand of my Wii. Long time ago I booted it without any issues.
But after months with little use of Dolphin, I tried to run it again and failed.Any time I try Dolphin freezes for seconds, shows some warnings and crashes.



Some info:

-I'm pretty sure the nand backup is perfect. In order to be sure, I redumped again with botmii, but it still didn't work
-I also tried a clean portable installation of Dolphin. The bug remains.
-Interpreter, LLE, graphic backens don't have any effect in this bug.
-Much older builds of Dolphin don't crash or crash much less. 5.0-1669 works fine. Tomorrow I'm going to test more builds until I find the first problematic one.
-The Wii I have is modded, so it could have something installed which would be incompatible with Dolphin. I installed some ciOS in the recommended final positions (like 250), the homebrew channel, some wads, botmii...) although I didn't do anything stupid like overwrite all official iOS with ciOS.
-Some wii homebrew like Gecko crashes like the NAND as soon as the emulated Wiimote is connected. Disabling the emulated Wiimote allows me to use the homebrew and I can even access the NAND after pressing "Exit" (then it can connect the wiimote without issues)

Do you have some advise for this problem?

PD: I knew creating a new NAND would overwrite my saves, so I exported all of them... but the import feature only let me import them one by one. Is there a way to add all of them together?

Edit1: Syscheck report about my NAND

The last build capable of running my NAND is 5.0-2124.
The first build which freezes trying to run it is 5.0-2127.

That build implements #4723 "Set up IOS RAM information area with real values.". Maybe there is a conflict between how it manages the iOS and the standard and hacked iOSes I have installed in my NAND.

My Syscheck report might give us some hints...

Maybe you're using an old system menu version (which requires an old IOS)? If so, PR 4907 will probably fix it. You can download a test build of it here: http://dl.dolphin-emu.org/prs/pr-4907-dolphin-latest-x64.7z

It works flawless. Thank you very much

My NAND is pretty updated (4.2E v482, the second latest one), so I wonder where did the old-iOS dependence come from.

4.2 is not the latest version and it uses an old System Menu IOS (IOS70). The newest one is 4.3 which uses IOS80.

Anyway, that's fixed in 5.0-2532.
