idaxex 0.1
Built for IDA Pro 7.2.
To install simply extract into IDA's 'loaders' directory (eg. C:\Program Files\IDA 7.2\loaders)
Recommendations
Recommend pairing this loader with the PPCAltivec plugin, to let IDA to understand any Altivec instructions. Fortunately yui-konnu has released an updated version for IDA 7 here: https://github.com/yui-konnu/PPC-Altivec-IDA
PPC2C also comes in useful for making sense of some of the bit-fiddling opcodes, the code for it can be found here: https://github.com/gibbed/ppc2c
You can also integrate Ghidra's decompiler into IDA by using cseagle's blc plugin, which works pretty well with both X360 executable formats (XEX / EXE).
Support
As there's only an x64 build of PPCAltivec I've decided to only release the x64 build of idaxex - to help make sure people don't accidentally load into the 32-bit IDA and lose out on Altivec support. (a 32-bit version of idaxex can be built, but IMO there's not really any point)
idaxex has no user-configurable options - just extract the loader, reload IDA and you should now be able to load XEX files!
If you have any problems please let me know about them on the Issues page!
