[Error : Midi] Unknown GMID chunk type: 285212672

I've tried your linux_port_implementation branch. The build went successfully, after installing some libraries.
When starting i get:

Note: I am using the original vanilla content from my CD from year 199?.
With which version did you test?

It seems that my SOUNDS.GOB is not compatible.

I veryfied with at fresh GOG installation that this gives the same error.

So I actually haven't gotten back around to the post "getting it to even build" troubleshooting. Been incredibly busy with my day job, one of these days I mean to swing back around to this but it's been low priority. There were some areas in the standard format extractors I had to switch from basic C types to stdint types to ensure the alignment was correct, you may want to check if the GOB formatter is actually honoring alignment.

Other thing is what is your host? I didn't do any endianness analysis while touching up the file parsers, I wouldn't be surprised if it isn't endianness-friendly.
