Flashing the ROM: Some linker devices allow you to flash a combined Sonic 3 & Knuckles ROM directly. This process involves using software provided with the linker to load the patched W Sonic 3 Bin file onto the device.
Gameplay: Insert the cartridges into the Genesis or Mega Drive console and play through the combined Sonic 3 & Knuckles experience. Error #4: The file is named wsonic3

Using Emulator Lock-On Features

Some advanced emulators can simulate the physical cartridge lock-on without a pre-merged ROM.

BlastEm: Load Sonic & Knuckles.bin first. Then go to File → Lock On → select Sonic 3.bin. BlastEm will dynamically combine them in memory.
Kega Fusion (hidden feature): Load Sonic & Knuckles, then go to File → Cartridge A → Load ROM and select Sonic 3. Fusion will treat it as a lock-on.
BizHawk (for TAS): Use the “Sonic 3 & Knuckles” configuration wizard.

Verdict: The dynamic lock-on is more accurate, but it is slower to set up each session. A permanent wsonic3.bin is more convenient.
