When i put a game in the sega it dosn't read the game and the screen goes green.

Depending on how you are looking it up, you would need to be on channel 3 or 4 on cable or antanna if it's hooked up on the RF. If you are using the yellow and white and you don't have a yellow port put it in the green port. But the best why to get it hooked up is by HDretrovision cables, it will give you the best picture. But the cables are not cheap.

ounds like the reading head may be damaged or misaligned.

Hi,

Looks like your Dreamcast can't read the game properly either due to damaged disc or the dreamcast GD rom is not working properly. try recalibrating the GD rom using this guide: http://www.youtube.com/watch?v=HTMSRfEqWAU

Well maybe your segas mechanics in the inside of it are starting to break down then.

Your spindle motor has gone, this is not impossible to solder another one in, and should be considered as these Sega consoles are getting rare over time. You will notice that it will attempt to read the disc but will just stop after 3 seconds, failing that open the machine and put a bit of tape at the back of the GD drive where a little lever is to keep it down as the lid maybe out of alignment.

Have you cleaned the Sega? What I mean is where the casset game goes. Push down the little flap, and there should be a little strip with contacts on the inside. Just clean it with a cotton swab and alcohol. And also, clean all your games also the same way.

Hope this helps.

put a disc in
press button b several times
the game should not start (if it does then press the reset butoon and try again)
you should get the green and blue screen
there is a button called memory
select the button by pressin A
this should give you the status of your memory
then press A again to get into the Memory menu where you can format, move or erase your data
enjoy!
