MVS is the better choice,no cencorship in games,games are much cheaper than there aes counterparts and even the newer games although start of expensive drop in price quicker than the aes ones,take for example at the moment i would say kof 2000 is abou the same price on both formats but MOTW is 400 plus on aes but only 100 on mvs,last blade 2 is 200 on aes only about 60 on mvs and it is not censored because unless you have a debug chip on the aes you cant access fatalities or blood while on the mvs you can,the biggest price difference though is on metal slug,for a genuine copy on the home system it wil sert you back about a thousand dollars.you get the excact same version on mvs woith red blood for about 40,now thats a huge saving,get it while you can <IMG SRC="smilies/smile.gif" border="0">as i know a lot of people are starting to opt for mvs now and with the 1 slot, i myself have a super gun and if you do get this adaptor from arcade make sure it can play all games as i know snk put a chip in there games from 99 onwards so that there games after that date cant be accessed via some converters.
