hmm. i've checked all of the samples at mphq (samples/real/*) and none
of the fps words are >30, but the next word after the second fps field
(currently ignored) is really the non-integer part of it:

###FPS### 0x19 25
###FPS2### 0x0 0
###FPS### 0x1E 30
###FPS2### 0x0 0
..
###FPS### 0xE 14
###FPS2### 0xFC20 64544
###FPS### 0x1D 29
###FPS2### 0xF852 63570
###FPS### 0x17 23
###FPS2### 0xF9C4 63940

14+(64544/65536) = 14.984863 (~=14.985)
23+(63940/65536) = 23.975647 (~=23.976)
29+(63570/65536) = 29.970001 (~=29.97)
