This here was something I decided to create using FL Studio, a few MIDI files, and a ton of soundfonts from the DS Pokemon series (and the Game Boy soundfont).

Note: Not all are mine, but I did most of these. A few were on YouTube done by Red6095 (they're more for the fact that they're awesome, and anything I tried to make couldn't match up, plus it completed the set), and these are those tracks:

16 Battle! Vs Trainer in Johto (B&W - HGSS)
19 Battle! Vs Raikou (B&W - HGSS)
27 Battle! Vs Suicune (B&W - HGSS)

With that I sincerely suggest you check out his stuff as he's much more talented than me: Red6095's Channel - YouTube (http://www.youtube.com/user/Red6095)

Anyways, here is the set itself: DOWNLOAD (http://www.multiupload.com/AGIVB45QD6)

The tracks have been titled thus:

Track name - Soundfont origin - Game origin

So, for instance:

05 Battle! Champion Gary! (HGSS - RBY)

Means:

Track 5, Battle! Champion Gary! using soundfonts from heartGold/SoulSilver, from the game Red/Blue/Yellow.

I'm working on a similar set for Sonic the Hedgehog which I hope to have done this week.
