[Yagi] ERROR : No sleigh specification for PowerPC:BE:16:default

[p0358]

This happens when Yagi is attempted to be used with a xex file from Xbox 360:

[Yagi] INFO :  load compiler with sleigh id : PowerPC:BE:16:default
[Yagi] ERROR :  No sleigh specification for PowerPC:BE:16:default

The file is loaded into IDA using this loader: https://github.com/emoose/idaxex

Would appreciate a fix since PowerPC is declared to be supported, so it's probably something simple, thanks in advance

[p0358]

Apparently this is a problem with using IDA64 for a 32-bit file. When using IDA (32-bit), the file gets detected with

[Yagi] INFO :  load compiler with sleigh id : PowerPC:BE:32:default

and Yagi seems to work. The reason I loaded IDA64 was that my 32-bit installation was broken, but I fixed that problem for now.

So I guess my issue is solved, but not sure if I should close this? I guess the decision depends on whether IDA64 and Yagi are supposed to work with a 32-bit executable. I know for example Hex-Rays refuses to decompile on such configuration for x86 architectures. It might even be a problem with idaxex, in which case it wouldn't be relevant here in the first place.
