Interesting. I know very little about PPC, but wanted to have a look at MDG1 to see if it was Tricore as I've done a lot with Bosch Tricore and understood that MDG1 could be built for Tricore or PPC, but the binary I have is not Tricore but I could not get official (but out of sub) IDA 6.95 to make any sense of it, probably an MPC57xx.

PPC supports instruction compression, it can be that the file is compressed, in this case you need to somehow dump the dictionary from the processor that was used to compress the data.
For example gearbox files (GS19) have the same issue, the code is compressed and decompressed in-place during execution...

No compression, it is VLE, so you have to select VLE
