Hey there....
The introduction music from Golgo 13: Top secret episode/The mafat conspiracy (as both's introduction music is same)-nintendo console, just grabbed my attention. I heard that again and again. It will be a lovely experience to hear a slow (low BPM) variation of the original one, as original seems to be running out somewhere.
For referrence, here is the midi link of the original one:

Thanks in advance
