awhite2600 Posted March 22, 2008 Share Posted March 22, 2008 (edited) I picked up two cartridges at a flea market today. I'm located in Canada. The carts are labled in an Asian language. Both carts have the same front label, but the backs and ends are different. As you can see in the pics, the carts are slightly bigger than a 2600 cartridge. The edge connector is wider than a 2600 cart. Does anyone know what system these are for? Thanks.

snorlaxnut Posted March 23, 2008 Share Posted March 23, 2008 I think they are for the Sega Mark III (Japanese version of Sega Master System). Quote Link to comment Share on other sites More sharing options...
Wickeycolumbus Posted March 23, 2008 Share Posted March 23, 2008 I think they are for the Sega Mark III (Japanese version of Sega Master System). Dito. Quote Link to comment Share on other sites More sharing options...
y-bot Posted March 23, 2008 Share Posted March 23, 2008 They definitely look like SG-1000/MK III games but I've never seen any with a yellow case like that. y-bot Quote Link to comment Share on other sites More sharing options...
awhite2600 Posted March 23, 2008 Author Share Posted March 23, 2008 Hmmm... Thanks for the info. So I wonder if they will work on a North American Sega Master System or Genesis with a Converter. Quote Link to comment Share on other sites More sharing options...
awhite2600 Posted March 23, 2008 Author Share Posted March 23, 2008 I did some research and I guess the SG-1000/Mark III is different enough from the SMS that the games are incompatible. The MKIII has an extra sound chip and uses carts with a different pinout. y-bot claims to have never encountered games like this in yellow shells. Could these be pirate carts or something rare?

y-bot Posted March 24, 2008 Share Posted March 24, 2008 I looked at some lists of games and didn't see anything with part numbers like that. Maybe try emailing someone at smspower.com or some other Sega fansite. y-bot Quote Link to comment Share on other sites More sharing options...
smspower Posted July 5, 2008 Share Posted July 5, 2008 Based on the pinouts, and pins B21/B22 being grounded I would say they could be unlicensed SG-1000 cartridges.
