MemoryAccessor - Pythonic way to read and write the memory

class desmume.emulator.MemoryAccessor(signed, mem: DeSmuME_Memory)

Bases: object

Pythonic accessor class for manipulating the memory.

Access a single unsigned byte of memory at offset 0x100:

>>> emu_memory = DeSmuME().memory
>>> emu_memory.unsigned[0x100]
<<< 3

Access a subset of the memory as bytes:

>>> emu_memory = DeSmuME().memory
>>> emu_memory.unsigned[0x100:0x200]
<<< bytes(...)

Access a subset of the memory as signed integers:

>>> emu_memory = DeSmuME().memory
>>> emu_memory.signed[0x100:0x200]
<<< [-3, 2, ...]

Access a subset of memory as 4-byte unsigned integers:

>>> emu_memory = DeSmuME().memory
>>> emu_memory.unsigned[0x100:0x200:4]
<<< [-236, 1002, ...]

Writing to memory works the same way. It doesn’t matter if you use the signed or unsigned accessor for this, both work the same:

>>> emu_memory = DeSmuME().memory
>>> emu_memory.unsigned[0x100] = 2

You can also use the read_* methods instead for a more verbose way to read the memory as integers. For writing those methods can be found in the DeSmuME_Memory parent object.

Should not be instantiated manually!

read_byte(addr: int) → int

Read a 1-byte size integer at the specified address.

read_long(addr: int) → int

Read a 2-byte size integer at the specified address.

read_short(addr: int) → int

Read a 2-byte size integer at the specified address.
