Hi ya'll....
I'm looking to buy a working Yobo clone GN-TWIN system, loose or complete, any model color (silver or black).... But the Sega Side must have the TECTOY-580G chip, if you are asking yourself how can I tell?.....You have the following options.... 1- either look closely at the Sega cartridge connector compartment,you'll probably see the tectoy label written in the GOAC chip (It must say TECTOY)...2.- Open the the system shell to fully access the motherboard and reveal the tectoy chip....If it doesn't have the tectoy chip then I'm not interested...I believe any of the few first GN-TWIN batches have this particular chip....Please PM me your price....Thanks in advance!
