had the wifimax to start with but it kept giving me tons of grief. Barely seeing it, I had to configure the damn thing everytime I used it.
Got the nintendo one and it just kind of plays itself. It's great. Would recommend highly over the wifimax.
I didn't know they made an MSU cart for the Genesis.... I knew about the SNES one and the library for that is rather large but the Genesis one has very few games
