Super NES Programming/Initialization Tutorial/header
Bazz wrote almost this entire header. Use it in your own code!

.MEMORYMAP ; Begin describing the system architecture.
SLOTSIZE $8000 ; The slot is $8000 bytes in size. More details on slots later.
DEFAULTSLOT 0
SLOT 0 $8000 ; Defines Slot 0's starting address.
.ENDME ; End MemoryMap definition
.ROMBANKSIZE $8000 ; Every ROM bank is 32 KBytes in size
.ROMBANKS 8 ; 2 Mbits - Tell WLA we want to use 8 ROM Banks
.SNESHEADER
ID "SNES" ; 1-4 letter string, just leave it as "SNES"
