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.
Error Codes[edit]
Error Code | Description |
---|---|
D9012FF1 | Address is misaligned |
E0A12FF9 | Service is already Initialized |
E1612FF7 | Provided Kernel Handle is invalid |

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). |
