Ok this probably isn't on the lines that you were thinking of but it should
still improve speed a teeny little bit.

When doing for loops do -- instead of ++, apparently the Playstation is ever
so slightly quicker at --

For example

int i
for(i=100000,i!=0;i--)
{
    printf("Hello world\n");
}

Hope that helps
