[Error] Fatal error before kernel init

[PredatorCZ]

Using IDA 7.0, shows every time I try to load main, sdk or subsdk files. Tested on Mario Kart8, Xenoblade 2, Monster Hunter XX.

Do I need to set anything specific?

[pgarba]

So far I verified all binaries in the SDK and had no problems with them. I will try to look into the game binaries too.

[pgarba]

How did you extract the binaries from the xci ?

[PredatorCZ]

hactool for both xci and nca, you will need keys, they are on net, binaries are in section 0 of nca

[pgarba]

I just tested with IDA 7.1 on Wonderboy and Mario Odyssey both. Both worked for me.

Did you rename the loader to "Switch64.dll" and copied it to the "loaders" directory ?

[pgarba]

Ok got the problem...

Mario Kart is an ARM 32 binary. Didn't even know that the Switch supports 32bit binaries.

[PredatorCZ]

Thank you for looking into this. I suppose it's adress size related problem then.

[pgarba]

Yes, all structs I reverse engineered are 64bit. I need to create a 32bit IDA loader and RE the 32bit structs

[PredatorCZ]

Instead of recreating each struct, wouldn't be better to use typedefs and switch them with macro? So if you'll need to edit some of them, you dont need to do each thing for both architectures. I don't want to be annoying, just want to help.

[pgarba]

Thats what I'm doing but sometimes the entries are different for 32bit and 64bit. so its a little bit more work then just makeing the types 32bit.

Hello, It has been a few days. Just checking the state.

[pgarba]

Hey,

I'm at the RECON right now. When I'm back home I think I will find some time to fix it.

[pgarba]

Sorry that it took me that long. Should befixed now!

[PredatorCZ]

Thank you very much.
