As I proposed to Ayla and DarkstackDev, here is the code I use to test the custom resolution settings :
/*
File : resolution.c
Let's test the resolution !
*/
#include <stdio.h>

loadImage((int *)((int)&(txr)),"/rd/resol.png",1024,0,0);
/* Go as long as the user hasn't pressed start on controller 1. */
while(!check_start()) {
do_frame();
}
return 0;
}
As you can see I need to set up the resolution before pvr_init and after.
