Im going to get a Neo Geo MVS in 2 days but I keep hearing about this bio chip. I know you do not have to install it but it gives you all the features that the AES games have. What I want to know is it that hard to install one if you never did anything like this before? Also does a US MVS have those memory card slots where you can save the data you did or is that only in Japan. Thanks for the help everyone
