Reset vector with 2K ROM

Wed Jun 15, 2016 2:51 AM

Hi, as I understand it when the 2600 is powered on the PC is set by the reset vector, which is held in ROM memory locations $fffc & $fffd. But when a 2K ROM is inserted the ROM only reaches up to $f7ff. When I look at the hex dump of Combat I can see the reset vector ($f000) in locations $f7fc & $f7fd.


So does the reset vector location depend on the ROM size or am I missing something ?
