When in <code>Legacy</code> mode, the actual memory layout is the same as in <code>New3DS Prod</code>, except the available application memory as reported to the application is reduced to the Old3DS size. | |||
The exheader value for the New3DS system mode value must be ≤ to the <code>AccessDesc</code> value, otherwise the invalid-exheader error is returned. | |||
