I picked one of these up yesterday and as an avid Sega lover and fan of the megadrive days in particular I only have 1 thing to say...
AVOID THIS LIKE THE PLAGUE, it is absolutely woeful, the sound output is apalling compared to a normal megadrive and it runs games slow, and 50% of my carts are glitchy...the other 50% refuse to load stating the error message "only for use on Pal / Secam megadrives" and this happens on NTSC or Pal modes, so in essence this is a useless piece of tat
Will be returning to Game tomorrow morning and then buying a replacement megadrive off ebay since my original finally bit the bullet some months back
Very gutted indeed as I figured this was a neat solution
