Technical notes

Retro Engine v3 decompilation of Sonic CD (2011 Christian Whitehead mobile/Steam port). Single binary; one data pack per install.

CheckRSDKFile only fopen()s the pack; there is no signature test. If the file is absent the engine falls back to a loose Data/ tree. When GameConfig.bin cannot be loaded either way it writes usage.txt describing the layout it wants. ref: RSDKv3/Reader.cpp:26-87 (CheckRSDKFile), RSDKv3/RetroEngine.cpp:283-321, RSDKv3/RetroEngine.cpp:329-366

settings.ini key Dev:DataFile overrides the default "Data.rsdk". ref: RSDKv3/Userdata.cpp:352-353,467-468, RSDKv3/RetroEngine.hpp:437

Bytecode detection probes two layouts in order after the pack opens: Data/Scripts/ByteCode/GlobalCode.bin (BYTECODE_MOBILE) or GS000.bin (BYTECODE_PC). Either lives inside Data.rsdk when the official pack is present. ref: RSDKv3/Reader.cpp:54-82

• System: soniccd
• Source: RSDKv3/Userdata.cpp:352, RSDKv3/Userdata.cpp:467-468, RSDKv3/RetroEngine.cpp:302-305
• Sonic CD assets (RSDK v3 container). Shipped with the official Sonic CD release (Steam, iOS, Android, Sonic Origins). The engine opens the file with fopen(); content is validated by trying to load Data/Scripts/ByteCode/GlobalCode.bin or GS000.bin from inside, not by hashing the pack.
