-changed the memory management yet again, now just use the mem which has enough space left instead of fixed memory in most parts -fixed alot of things about banner playing, now shouldnt randomly codedump anymore or things like this, also some banner sounds which did not play before should work fine now -removed unused code and added better debug prints -using some fixed voice for game banner and not always a new one per banner -fixed DIOS-MIOS cheats for sure now :P -fixed possible memory allocation bug in wbfs alloc (thanks to cfg-loader) -removed MEM2_memalign since it did not work correctly -fixed a few wrong memset sizes
