Hey Paulo, I don't think there's anything to be concerned about here.
A) The DS hardware doesn't do reverb like that, nor does it sound like it's supposed to be a MIDI file. I know that's your're doing too since I rip the games to condense into an instrument pack for music production and there has been nothing like that ;P
B) Some of the notes you're hearing that "sound strange" are just notes you don't hear in the actual tracks too well due to how the instrumentation is overlayed on a sequence.
C) These are all sequences, they don't loop at all so it further means that your built-in DLS Windows player is making these very interesting instrumental sound the way they are.
Until we see the original sound data sequences+DLS posted here, I'm convinced that it's just your soundcard making MIDI files sound pretty unique.
@Sligneris, you're close, but the instruments that you hear in-game...Don't exist at all in these versions.
...Did you use a certain Trans tool to peek into the sound data : ?
It's possible that it is my soundcard because I am on a notebook. I will test with my PC when I'll be at home (friday).
I haven't changed anything in these songs, they are like I have found it when I ripped the game.
It was a *.sseq file that I converted in ah *.midi file and then in *.mp3 to put it online.
Same notes, exact MIDI's, played differently by my netbook's soundcard
Yours is generally going to sound better because (I assume) your computer models are pretty new compared to mine (my netbook is 4 years old and with a pretty generic soundcard, so it relies on the default Windows GS Syntfont DLS thing)
