Just recompiled but not found any noticeable improvement...but i want to take your attention on 2 things i'm experimenting.
Load of TTF font only on startup of the game and try to use mp3 files instead of ogg music files.
I have changed some code (but i'm not a programmer) and with mp3 music the game work but didn't hear nothing on output.
With TTF font i remember i've read from gp32x.de forum ( i think from "hmn" user ) this doc:
from
http://www.gp32x.de/board/index.php?/topic/55495-gaming-wiz-slow-with-sdl-ttf-h/?hl=%2Bttf+%2Bbenchmark#entry896721
Not loading the font every time should give a BIG speedup. I actually wrote a little benchmark for this:
Loading font every time -> 6 FPS
Loading font just once --> 195 FPS

I have added this but i have segfault...but maybe i have done something wrong.
Also i have commented out a line in main.c as suggested by an user on gp32x.de forum :
Code:

ciclo[0] ++;
else
ciclo[0] = 0;
if (ciclo[1] < 90)
ciclo[1] ++;
else
ciclo[1] = 0;
if (ciclo[2] < 8)
ciclo[2] ++;
else
ciclo[2] = 0;
