AGB Programming Manual AGB Memory 3.2.2 Game Pak Memory 1) Game Pak ROM Three 32 MB Game Pak ROM spaces are allocated to the area beginning from 08000000h. The access speed of each of these spaces can be set individually. Thus, they are named Wait State 0, Wait State 1, and Wait State 2. This specification enables memory of varying access speeds in Game Pak ROM to be accessed optimally. The base addresses of the 3 spaces are 08000000h for Wait State 0, 0A000000h for Wait State 1, and 0C000000h for Wait State 2. In addition, the upper 1 Mbit of each space is allocated as flash memory. This area is used primarily for saving data. 2) Game Pak RAM The area beginning from 0E000000h is the Game Pak RAM area. Up to 512 Kbits of SRAM or Flash Memory can be stored here. However, it is an 8 bit data bus. Due to the specifications, any Game Pak device other than ROM must be accessed using Nintendo's library. ©1999 - 2001 Nintendo of America Inc. 20 D.C.N. AGB-06-0001-002B4
