I have a Model 2 Sega with the proper Sega CD attached, and since I picked it up i've been having a problem with the unit restarting randomly.
If the Sega CD is connected, I get between 45-90 minutes of game play, then the light on the Sega flashes, and I go back to the CD start screen. If I immediately start playing again, I get about 20-30 minutes of play, then a restart. If I start playing again, I get 10-15 and so on. This lead me to think it might be an overheating problem, but feeling the power supplies and the consoles after they restarted - they weren't very warm.
I'm curious to know what might cause this, and especially how to fix it.
-Little bit of extra information. I do not use an official Sega power supply for the Genesis (I do for the CD). Instead I use a laptop power supply (12v, 830ma, I believe). If I use my Sega power supply (a Sega power supply I believe to be for the Model 2 Genesis (12v 850ma), the CD will not boot (it will boot the Genesis, although its only been power tested)
-I do not have the metal shield for the sega CD.
