I keep looking at those combo systems, but most of them are so poorly made that its hard to know if they are going to last more than a few days. Some family members bought one a while ago (different kind) and it lasted two weeks, which is a tragically common occurrence.
I almost wish Nintendo would just make a quality one for NES, SNES games but I doubt they ever will. Though I would be much more interested in a Genesis/ SNES one. Which isn't crazy given Sega's situation. (I can hear my 15 year old brain screaming NOOO from the 90's.)
