Mornin!



I am shure this topic egzists somwhere but I stopped searching,so accept my apologies.



and now the problem :

so I convert saves from .sav (tt) to .dat (m3.. old one not simply) with this http://www.shunyweb.info/convert.php or the other one it all goes ok,size is ok,but when I put save on m3 it loads like new,like nothing happend,I mean there arent my saves.. just new game.. i tried patching game,also with m3 manager but nothing worked.. ? 

thanx in advance!!!
