You can use any 9-12V 1A AC or DC power supply as long as the tip fits. Sega Mega Drive/Master System psu's are regularly mentioned as being suitable alternatives.
That being said, don't try and use a Snes AC power supply on a Sega DC console.
Thanks for the suggestion guys. Since I live in Norway we use the two pin plug isntead of 3 like in England. Would be great if someone had one of those so i dont have to buy adapter (Yes I am cheap) I forgott that i also need cables for av. If someone happens to have both ac adapter, av cables and on or two controllers then please pm me Thanks for the link Acid I will look into the products.
