I came across one while I was on vacation but they wanted way too much for it. I'm not that big of a gamer to shell out that kind of money for a hand held system, that and the fact I got rid of my Sega and games Years ago.
It appears to be a handheld console by Blaze International called The Blaze Portable game console. From the website itself, "The Blaze Portable game console is a video game player, which is pre-loaded with 20 classic games from SEGA. There is therefore no need to buy game cartridges. The blaze Portable game player has an A/V connector and with the included cable the player can be connected to any TV set. Enjoy playing classic SEGA games anytime, anywhere with the new Blaze Portable video game player. Presented in stylish blister packaging."
It claims to be the first Sega Mega Drive handheld console. However, Constantine's link has shown that their claim is complete bollocks, as the Sega Nomad was released way before this Blaze Portable.
