MOD

MOD describes a module object. It is essentially a replacement for a PT_DYNAMIC program header.

ModuleHeaderLocation

This is "nn::rocrt::ModuleHeaderLocation".

Offset	Size	Description
0x0	0x4	[17.0.0+] Version ([1.0.0-16.1.0] Padding)
0x4	0x4	HeaderOffset
0x8	0x4	[17.0.0+] VersionOffset

ModuleHeader

This is "nn::rocrt::ModuleHeader".

Offset	Size	Description
0x0	0x4	Signature ("MOD0")
0x4	0x4	DynamicOffset
0x8	0x4	BssStartOffset
0xC	0x4	BssEndOffset
0x10	0x4	ExceptionInfoStartOffset
0x14	0x4	ExceptionInfoEndOffset
0x18	0x4	ModuleOffset (offset to runtime-generated module object, typically equal to .bss base)
0x1C	0x4	[19.0.0+] RelroStartOffset
0x20	0x4	[19.0.0+] FullRelroEndOffset
0x24	0x4	[19.0.0+] NxDebugLinkStartOffset
0x28	0x4	[19.0.0+] NxDebugLinkEndOffset
0x2C	0x4	[19.0.0+] NoteGnuBuildIdStartOffset
0x30	0x4	[19.0.0+] NoteGnuBuildIdEndOffset

ModuleVersion

With [17.0.0+] this structure is normally located immediately after the ModuleHeader. This stores the nnSdk version.

Offset	Size	Description
0x0	0x4	Major
0x4	0x4	Minor
0x8	0x4	Micro
