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 |

Version history[edit]
| Version | Changes |
|---|---|
| v0 | Initial version. |

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). |
