+notes: |
+  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 just fopen()s the data pack; there is no signature or
+  checksum test. The engine falls back to a loose Data/ + Bytecode/ tree
+  if the pack is absent, and writes a usage.txt that asks for a pack named
+  Engine.dataFile[0] (default "Data.rsdk").
+  ref: RSDKv4/RetroEngine.cpp:296-331, RSDKv4/Userdata.cpp:251-263,
+       RSDKv4/RetroEngine.cpp:484-521
+
+  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.
+  ref: RSDKv4/RetroEngine.hpp:373, RSDKv4/Userdata.cpp:396-408

+    note: |
+      Sonic the Hedgehog (2013) assets. Shipped with the official Sonic
+      Origins release and the delisted iOS/Android apps. Engine opens the
+      file with fopen(); content identity is read from the embedded
+      GameConfig.bin, not the pack hash.

+      Sonic the Hedgehog 2 (2013) assets. Shipped with the official Sonic
+      Origins release and the delisted iOS/Android apps. Same engine
+      filename as Sonic 1; the launcher selects which pack sits next to
+      the binary at run time.
