In cases where `dmnt` has not activated the cheat manager, but the user wants to make it do so anyway, the cheat manager's service API provides a `ForceOpenCheatProcess` command that homebrew can use. This command will cause the cheat manager to try to force itself to attach to the process.

In cases where `dmnt` has activated the cheat manager, but the user wants to use an alternate debugger, the cheat manager's service API provides a `ForceCloseCheatProcess` command that homebrew can use. This command will cause the cheat manager to detach itself from the process.
By default, all cheat codes listed in the loaded .txt file will be toggled on. This is configurable by the user by editing the `atmosphere!dmnt_cheats_enabled_by_default` [system setting](configurations.md).
