The mapadress used in these services is calculated by the user-process like so: when inputaddr is <0x08000000, the address used is the same one from inputaddr. Otherwise, the address is: mapvaddr = inputaddr - (0x08000000 - <main-process .text address + .text, .rodata, .data, and .bss size aligned to pagesize>). This service API is used for CTR "DLLs"/shared libraries: [[CRO0|CRO]].

The mapadress used in these services is calculated by the user-process like so: when inputaddr is <0x08000000, the address used is the same one from inputaddr. Otherwise, the address is: mapvaddr = inputaddr - (0x08000000 - <main-process .text address + .text, .rodata, .data, and .bss size aligned to pagesize>). This service API is used for CTR "DLLs"/shared libraries: CRO.

Version historyEdit

Version Changes
v0 Initial version.
v1024 Removed access for SVC's: 5,7,D,E,10.

Cmd5 now sets the last segment in the CRO binary to R-X when it's done.

Maybe more.

v2049 No changes.
v3074 Added cmd9.
v4096 No changes.
v5120 No actual changes, just a rebuild with latest CTRSDK(only the CTRSDK version values in .code for ErrDisp were updated).
