Droid Developer Kit CD (_ddk.exe)

The 1999 Droid Developer Kit (9748) CD-ROM application is a building-instructions and media player, not a programmer for the Micro Scout. (The Dark Side Developer Kit (9754) shipped a comparable CD; only the 9748 disc is analysed here.)

What it is

A C++ engine (_ddk.exe, namespaces LEGO::DCL::BuildingInstructions / StorageSystem) that renders its UI with DirectX and plays ~1244 QuickTime clips. Content is data-driven via LEGOModule descriptors (intro / build / tip clips per step).

No VLL on the disc

Binary analysis confirms the disc cannot program the Micro Scout. The executable, unpacked from DATA1.CAB, has a C++ RTTI class table containing only building-instructions / media-player classes (BuildScene, StorageSystem, DirectX + QuickTime). It has no VLL / light-link / transmit class and no serial/parallel/COM port access; the Micro Scout appears only as UI bitmaps.

The Micro Scout's 7 programs are fixed on-brick (mode dial); the blank "P" slot was reserved for a "future application (fall 2000)" to be delivered via the RIS 2.0 USB tower (LEGO FAQ — P program & IR tower), which LEGO never shipped.
