| kip1={SD folder}/* | Loads every .kip/.kip1 inside a folder. Compatible with single kip1 keys. |
| fss0={SD path} | Takes a fusee-secondary binary and `extracts` all needed parts from it. kips, exosphere, warmboot and sept. |
| fss0experimental=1 | Enables loading of experimental content from a FSS0 storage |
| exofatal={SD path} | Replaces the exosphere fatal binary for Mariko |
| kip1patch=patchname | Enables a kip1 patch. Specify with multiple lines and/or as CSV. If not found, an error will show up |
| fullsvcperm=1 | Disables SVC verification (full services permission) |
| debugmode=1 | Enables Debug mode. Obsolete when used with exosphere as secmon. |
