Boot to last bank

"The mapper will not work properly unless both ports are in output mode, so after reset this should be done at first. All 32K PRG ROM banks should contain the reset code due to this, since otherwise the I/O ports are in input mode and won't assert any logic signals."

Would pull-up resistors on the PRG bank lines allow predictable booting to the last bank? --Tepples (talk) 08:16, 29 June 2013 (MDT)
