Its very much in its early stages but uses PRJ original Me7 script to load ME9 files, I've used Basano and 1 others previous posts to create this, Version 1 will load the file for you a simple selection of the ROM and then C will do the analysis for you.
Version 2 also loads the split maps from 1c0000 to 1fffff and has the original Analysis GUI , but as such untested.

Also as I did this with IDAPRO 5.1 it doesn't have the SDA (r13) address listed so the variables arenot shown correctly. I have version 6.1 as well and once I have tested I will upload to both versions.

Like I say it's not perfect but at least it loads it up and gives you a disassembled view of your file..
Now with V6.1
V6.1_v2 with Analysis GUI added

I found a version of IDA Pro v6.8.150423 and changed the script's first line to "WinWaitActive("IDA v6.8.150423")"

And it runs OK now. I can see now that the IDA Free version I had was not able to decompile PowerPC processors, specify TOC address etc.
