I decided to return the Atari Flashback 4. I did find at another Dollar General a Sega Genesis Classic Game Console which has 40 genesis games and 40 throw away mini games. It has 2 wireless controllers and 2 ports to use regular Genesis controllers. What sold me is that it has a cartridge slot that will accept almost all Genesis and Mega Drive (import Genesis for those who don't know) games. It was $40
Here is the complete list of Genesis games: Alex Kidd, Alien Storm, Altered Beast, Arrow Flash, Bonanza Brothers, Chakan, Columns, Columns 3, Comix Zone, Crack Down, Decap Attack, Ecco, Ecco 2, Ecco Jr., E-Swat, Eternal Champions, Fatal Labyrinth, Flicky, Gain Ground, Golden Axe (all three), Jewel Master, Kid Chameleon, Mean Bean Machine, Ristar, Shadow Dancer, Shinobi III, Sonic 3D Blast, Sonic and Knuckles, Sonic Spinball, Sonic the Hedgehog (1 & 2), Streets of Rage (all 3), The Ooze, Vectorman (1 & 2), and Virtua Fighter 2.
