Soundfont to make Fluidsynth sound much more like PortMIDI or SDL

[Death Destroyer - 4.7m4d]

I am trying to encode a demo using the video capture encoder that comes with prboom-plus . The music in this certain level with fluidsynth is CRAP , it sounds much better with SDL or PortMIDI . Does anybody know of a soundfont to make fluidsynth sound more like SDL or portmidi?

It does not have to be exactly the same , just very similar if possible.
