0x80000000 0x817FFFFF 24 MB MEM1 Memory (Caché)

The IOS Heap range is 0x933E0000-0x93400000 it is shown in registers 0x80003130(Start), 0x80003130(End). The top of MEM2 memory is allocated to Starlet. You can access this memory by disabling memory protection via hardware registers in Starlet. (See Starlet Register List. TODO).

0x80003400 0x100 NAND boot vector (Broadway initialization code from nandloader)
0x80003F00 0x132c100 (~19.2MB) Standard application executable area
0x81330000 0x4d0000 (~4.8MB) Loader executable area

Applications should use the 0x80003F00 - 0x81330000 area for executable code and data loaded as part of their ELF/DOL, while loaders should use from 0x81330000 onwards. Applications can use the loader area and MEM2 as data work space once they are running, but they should restrict the sections contained in the DOL or ELF to the executable area only, since MEM2 is reserved as work area for the loader at that time. To preserve "return to loader" functionality, applications should never use the 0x80001800-0x80003000 area.
