Lua Random Number Generation
// taken from http://snes9x-rr.googlecode.com/svn/trunk/snes9x-151/lua-engine.cpp
// http://snes9x-rr.googlecode.com/svn/trunk/snes9x-151/SFMT/SFMT.c
// same as math.random, but uses SFMT instead of C rand()
// FIXME: this function doesn't care multi-instance,
// original math.random either though (Lua 5.1)
static int sfmt_random (lua_State *L) {
lua_Number r = (lua_Number) genrand_real2();
switch (lua_gettop(L)) { // check number of arguments
case 0: { // no arguments
