reswitched / loaders Goto Github PK

Something is wrong with loading Unity games executables.
I have tried Mages of Mystralia and Serial Cleaner.
First one have mostly trash code. I have found only Steam part correctly disassembled.
Second one after couple of minutes is looped around Steam part.

So something with Steam-releated code is messing up loader.

idaapi.set_imagebase(loadbase)

please consider adding this in load_file because other scripts might need this info.

i installed the modules but when i put it in ida/loaders it didnt work for me as it didnt existed
please help

Fresh install of Windows 10 and IDAPR0 7.0

I get the following assertion when loading test_helloworld.nro

/Applications/IDA Pro 7.0/ida64.app/Contents/MacOS/loaders/nxo64.py: Traceback (most recent call last):

Certain kip1 files (e.g.: Loader) can have a discrepancy between the SectionHeader's CompressedSize and the compressed_data_len field in the footer.

Currently, a difference of one byte is detected in nxo64.py's line 30, but differences of up to 3 bytes have been detected.

every time I try to install this loader I have issues.

Can you please halp me find a definitive way to install this for IDA 7.0

Fresh install on current Windows 10

Cant seem to get a good decompile of this with the loader. xrefs are broken, and a limited amount of stuff is decompiled.

I have tried 2 latest versions of nxo64.py on Mortal Kombat 11 patched to newest version and Final Fantasy XII also patched. Always get the same error. For other games that I tested (like FF X) is still working.

I'm having trouble to use nxo64.py using IDA 7.5 and running Python 3.9.6:
undefined function __plugins__nxo64.PLUGIN_ENTRY
lz4 is already installed (latest version) and my IDA has the 3.9 support pack.

NxoException: invalid MOD0 magic.
it fetch 4 other characters : '\x01\x00\x00\x14'
