Shared Retro Engine v4 decompilation driving the 2013 Christian Whitehead
|
|
mobile ports of Sonic the Hedgehog and Sonic the Hedgehog 2. One binary
|
|
per build; the game identity is derived from the GameConfig.bin inside
|
|
the loaded data pack (gameWindowText "Sonic 1" or "Sonic 2").
|
|
ref: RSDKv4/RetroEngine.cpp:423, RSDKv4/ModAPI.cpp:428
|
|
|
|
CheckRSDKFile opens the data pack and compares its first six bytes to
|
|
the "RSDKvB" signature; there is no checksum test. The engine falls
|
|
back to a loose Data/ + Bytecode/ tree if the pack is absent. When
|
|
GameConfig.bin cannot be loaded either way it writes a usage.txt that
|
|
asks for a pack named Engine.dataFile[0] (default "Data.rsdk").
|
|
ref: RSDKv4/Reader.cpp:25-102, RSDKv4/RetroEngine.cpp:296-331,
|
|
RSDKv4/Userdata.cpp:251-263, RSDKv4/RetroEngine.cpp:483-520
|
|
|
|
Up to four packs can be mounted (DataFile, DataFile2..4 in the Dev
|
|
section of settings.ini); the extras default to Data2.rsdk, Data3.rsdk,
|
|
Data4.rsdk once declared.

note: |
|
|
Sonic the Hedgehog (2013) assets. Shipped with the official Sonic
|
|
Origins release and the delisted iOS/Android apps. The engine checks
|
|
the six-byte signature only; content identity is read from the
|
|
embedded GameConfig.bin, not the pack hash.
