Prior to 3.0.0, ro was included as part of Loader_services. Despite the separation, the service name ldr:ro is retained to maintain compatibility with old games.
ldr:ro, ro:1
[1.0.0-2.3.0] This is "nn::ldr::detail::IRoInterface"
[3.0.0+] This is "nn::ro::detail::IRoInterface".
[7.0.0+] ro:1 was added and is also "nn::ro::detail::IRoInterface".

LoadModule
Takes a PID-descriptor, 5 input u64s (client_pid_deprecated, nro_address, nro_size, bss_address and bss_size). Returns an output u64 (out_address).
UnloadModule
Takes a PID-descriptor and 2 input u64s (client_pid_deprecated and nro_address).
RegisterModuleInfo
Takes a PID-descriptor and 3 input u64s (client_pid_deprecated, nrr_address and nrr_size).
[7.0.0+] NrrKind must be 0 (User) for this function to succeed.
UnregisterModuleInfo
Takes a PID-descriptor and 2 input u64s (client_pid_deprecated and nrr_address).
Initialize
Takes PID-descriptor, a process handle and an input u64 (client_pid_deprecated).
RegisterModuleInfo2
Takes a PID-descriptor, a process handle and 3 input u64s (client_pid_deprecated, nrr_address and nrr_size).
First, this validates that the pid descriptor matches the pid for the process handle sent to this->Initialize() earlier. Then, this calls the same function as LoadNrr, except using the passed process handle instead of the one sent to Initialize.
When called from an ro:1 session, NrrKind must be 1 (JitPlugin). When called from ldr:ro session, NrrKind must be 0 (User).
ro:dmnt
This is "nn::ro::detail::IDebugMonitorInterface".

GetProcessModuleInfo
Same as GetProcessModuleInfo from ldr:dmnt.
