The one that comes with the DS browser.


First 16MB of the GBA ROM address range are all FF, except:

080000B2: 00 00 00 24 24 24 (signature?)
080000BF: 7F
0801FFFF: 7F
08240000: 32bit register; bit0: 1=enable RAM, 0=disable; other bits are always zero; initial value is 00000001

The register is the only thing that can be written to.


The 8MB at 0x09000000 are the RAM. Initially garbage-filled. When disabled, reads FF, but contents are retained (atleast for a certain time).


0x09800000 and up are open-bus.
