This is essentially an async wrapper for [[#GetApplicationControlData]], with support for multiple ApplicationIds.

==== Cmd421 ====

Takes an input TransferMemory handle, a type-0x5 input buffer containing an array of u64 [[NCM_services#ApplicationId|ApplicationIds]], an u8 [[#ApplicationControlSource]], an u64 size, returns an output Event handle and an [[#IAsyncValue]].

This is essentially the same as [[#ListApplicationTitle|ListApplicationTitle]] except the ApplicationControlSource is used here (ListApplicationTitle ignores it and uses 0xF0 instead).

The TransferMemory size must be at least: count*sizeof(u64) + count*[[NACP#ApplicationTitle|0x300]] + [[#GetApplicationControlData|0x1d000]].

The async task impl code eventually compares ApplicationControlSource with 0xF0, with a separate code-path being used when it doesn't match (which also handles [[NACP|compression]] when needed).

==== RequestCheckGameCardRegistration ====
