If this version value is less than a state field, the state field value is used instead (state field originates from [[System_Settings|system-setting]] <code>contents_delivery!required_system_version_to_deliver_application</code>).

Then this selects a [[#SystemDeliveryInfo]] with the latest version from the input array, ~~where~~ the ~~minimum version is~~ the ~~previously mentioned value~~. The version must ~~also be also~~ be at least the version value from the type-0x15 [[#SystemDeliveryInfo]] buffer. ~~This also does various validation~~, ~~etc~~. The ~~output s32 is an index~~ in ~~that~~ array ~~for~~ the ~~selected entry~~, -1 ~~if none found~~.

Then this selects the [[#SystemDeliveryInfo]] with the latest version from the input array. The output s32 is an index in that array for the selected entry, -1 if none found.

During the above loop it first calls the [[#SystemDeliveryInfo]] validation func, returning the Result on failure. Then it runs additional validation, with the [[#SystemDeliveryInfo]] entry being ignored on failure:

* The above latest-version value must be at least the version value from the type-0x15 [[#SystemDeliveryInfo]] buffer and the [[#SystemDeliveryInfo]] array entry.

* When HasExFat is set in the type-0x15 [[#SystemDeliveryInfo]] buffer, it must be set in the [[#SystemDeliveryInfo]] array entry.

* FirmwareVariationId in the type-0x15 [[#SystemDeliveryInfo]] buffer must not be 0xFF.

* UpdatableFirmwareGroupId in the [[#SystemDeliveryInfo]] array entry must not be 0xFF. The value must be within bounds of the settings array ([[System_Settings|sys-settings]] <code>contents_delivery!updatable_firmware_group_string</code>).

* PlatformRegion in the [[#SystemDeliveryInfo]] array entry and the type-0x15 [[#SystemDeliveryInfo]] buffer must match.

* Lastly when the following is true, this indicates success: (settings_array[UpdatableFirmwareGroupId] >> {above FirmwareVariationId}) & 1.
