Hello, I am very confused about this issue since there is conflicting information. The general consensus online is that +12 volt should be disabled when gdrom is removed, since it would cause excess heat with the gdrom removed. However the person I am buying my dreamcast from has told me that it is not necessary to disable the 12 volt, because the excess heat is caused by insufficient airflow, and that adding an sd card mount solves the airflow problem since it is the same shape as the gdrom.
He said that if the customer didn't order an sd card mount with the system, he would use a dummy load on the 12v to dissipate the heat, but because i have ordered the sd card mount it is not needed. Should I be satisfied with this explanation? Another thing is I am going to be using a Kaico adapter with the system which apparently requires the 12 volt to be enabled to work. Would adding a dummy load prevent the kaico adapter from working for some reason?
